Thread Subject: [Help] Printing problem in Mac OSX Leopard

Hi, my Macbook Pro had upgraded to Leopard. I found that Matlab can't print
out the figure I created. I got this error message:

'-----------------------------------------
??? Error using ==> graphics/private/send at 307
Error using ==> graphics/private/send at 129
Problem sending file to output device, system returned error :
lpr: The printer or class was not found.


Error in ==> printdlg>LocalInitFig at 469
  if LocalJavaPrintDlg( Data, Dlgname )

Error in ==> printdlg at 100
   Dlg=LocalInitFig(Data);

Error in ==> graphics/private/ppreview>onPrint at 906
printdlg(fig);
'-------------------------------------------

I can see the printer in the Print Window. But I can't print out the file.
Although I can save the figure as a PDF file and print it out without problem, I
still want to print the file directly under Matlab. Do I need to re-install
Matlab? Any idea to fix this problem? Thank you very much for your help.

You will probably need to contact support to resolve this. It may help
if you provide the info above as well as the output from the following:
   figure;
   plot(1:10);
   print -DEBUG

Note: if you're trying to print to something other than the default
printer then change the print command to

   print -DEBUG -P<printername>

where <printername> would be replaced by whatever name is assigned to
that printer.

The printcap entry for that printer may also be of use...

Hi Richard,

  Thank you very much for your comment. I may not address my question
clearly. My problem is about "Print" from the menu bar. When I create a
figure, I choose File -> Print Preview... from menu bar. Then I center the
figure, or stretch it to fill the page. Then I click the "Print" button. The error
message appears at this moment. It doesn't print out the figure. Same
condition happened when I click on the "Printer" icon on the tool bar.
However, I can print the figure using command "print" in the command
window. Following is an example of "print -DEBUG".

'-------------------------------------------------

So, it is confused to me that why command "print" works but not the "print"
button. I prefer to use the "Print Preview..." and "Print" button from the figure
window in case I want to adjust the figure position on the paper. This
condition didn't happen in Mac OSX Tiger.

Any idea about this problem? Any comment is appreciated.


Oh, one more question. When I use command "print", the data is sent to the
printer, but the printer doesn't print it out right away. The data receiving light
is flashing on the printer panel, and I have to stop by the printer and press
the print button to let the figure print out. If I don't, the figure will never be
printed. This is Weird. I didn't have this condition for older Matlab version.
This weird behavior happens both on Mac OXS Tiger and Leopard. Any idea ??


 I use Mac OSX Leopard, Matlab 2007a Student version.

You might want to verify that the name of the printer in the MATLAB
print dialog box agrees with the name of the printer as it is defined to
  your system - including capitalization/case of the characters.

The print toolbar button, the print dialog box, and print preview all
use MATLAB's print command (the same one you get when you type
print from the command line) - the GUIs simply set additional
parameters and/or figure properties before calling the print command.
If you're adventurous you can set a breakpoint in MATLAB's print command
with this command and investigate. To set the breakpoint type:
    dbstop in print
then print your figure from the dialog box. When the breakpoint is hit
display the parameters passed to print (simply enter varargin at the
MATLAB command line). This will let you see what the GUI is sending
(which may help identify the problem). To clear the breakpoint you can
enter the command:
   dbclear in print

I'm not sure at all why the command line print requires you to press the
print key on the printer... Since you have a postscript printer you can
try printing from MATLAB to a file and then sending that file to the
printer with the lpr command to see if that works (note the leading '!'
before the lpr command)
   print -dpsc test.ps
   !lpr test.ps
You can try the same lpr command from a shell prompt to see if it
behaves differently outside of MATLAB

Hi, Richard,

  Thanks a lot for the comment. I checked the printer name and was sure the
name is the same in both Matlab and Mac. The printer is a network printer,
which requires an IP address to connect to. Both Matlab and Mac use the
same IP address, and I only connect to one printer. I don't think Matlab could
connect to other printers.

  I tried to use breakpoint in print. I found 'varargin' has two cells.

varargin =

    [7] '-P128.95.xxx.xxx'

I don't understand the meaning of [7], but I know the second cell is the IP
address of printer. The breakpoint stopped Matlab in print.m file. When I
clicked 'Run' button from the tool bar, the error message appeared.

'-------------------------------------------
??? Error using ==> graphics/private/send at 307
Error using ==> graphics/private/send at 129
Problem sending file to output device, system returned error :
lpr: The printer or class was not found.


Error in ==> printdlg>LocalInitFig at 469
  if LocalJavaPrintDlg( Data, Dlgname )

Error in ==> printdlg at 100
   Dlg=LocalInitFig(Data);

Error in ==> graphics/private/ppreview>onPrint at 906
printdlg(fig);
'-------------------------------------------------

This condition occurred when I used 'Print Preview' window, same condition
as I mentioned before.

I also tested the 'print as ps file' function. It worked find and I can print out
the *.ps file from command line. I can print the *.ps file from Mac's shell too.
The only thing that didn't change was I still had to press the print button on
printer to print out the figure.

I noticed that the changes I made to the figure under 'Print Preview' window
was saved after I closes the 'Print Preview' window. So I can simply type 'print'
in command line to print out the modified figure. Although this is OK to me, I
still want to print the figure just by clicking the Print button.


Any idea about this problem? I really appreciate your comment. Thank you.

The [7] you see in the debug output is the handle of the figure being
printed... it's either the figure you created or a temporary copy
created by print preview.

I think the issue is that the operating system lpr command (used by
MATLAB to send the file to your printer) doesn't recognize the IP
address as a printer. I would expect that if you print to a ps file
(test.ps) and then from a system prompt (or using MATLAB's "bang"
command) if you executed the following you would see the same/similar
error.
 From MATLAB: !lpr -P128.95.xxx.xxx test.ps
 From a shell prompt: lpr -P128.95.xxx.xxx test.ps
(filling in the complete ip address, of course)

I think what you need to do is add the printer to your Mac, specifying
that it is an IP printer and entering both the IP address as well as
giving it a queue name, such as "networkprinter". Once that's done,
restart MATLAB and choose the queue name you specified as the printer to
print to (either from the list of printers shown in the dialog box or
with the print command's -P option

Hi Richard,

  Thank you very much for your response. The printer I am using has already
added to Mac' printer list. I use the System Preference --> Print & Fax to
setup the printer. Here is the info about setting the printer.

---------------------------------------------------
IP Printer
Protocol : Line Printer Daemon - LPD (this is Mac's default. The other two
options are "Internet Printing Protocol, IPP" and "HP Jetdirect - Socket")
Address : 128.95.xxx.xxx
Queue : (there's a note: "Leave blank for default queue." So I leave it blank)
Name : HP LaserJet 1320 (I name this printer.)
Location: (I leave it blank)
Print Using: HP LaserJet 1320 series (the driver for the HP printer)
---------------------------------------------------

After setting the printer, I view the general info of the printer.

-----------------------------------
Name: HP LaserJet 1320
Location: (blank)
Queue Name: HP_LaserJet_1320
Host Name: localhost
Driver Version: 4.0.0.080
URL: lpd://128.95.xxx.xxx/
----------------------------------

This works fine with the applications installed in my MBP, except Matlab.
I can see the printer "HP LaserJet 1320" in the list when I open Print Widow in
Matlab. But it got errors when I click "Print" button. As you mentioned, I can't
print the *.ps file by the command "lpr -P" under either Matlab command
window or Mac's bash shell. Why? What is the reason that the shell command
can't recognize the printer? However, if just use command "lpr", the printing
works fine, except that I have to stop by the printer and press the "Print"
button.

I had tried to restart Matlab and MBP several times, and it was no good.

I think that command "lpr" would print the file by the default printer, and this
sends the signal to Mac's default printer. In Matlab, it looks like the "print"
command tries to use "lpr -P" command, which doesn't work. This is weird to
me. Before I upgraded my Mac OSX to Leopard, the printing had no problem
in Matlab under Tiger. After upgrading, I re-set the printer and the problem
occurred. There's mystery somewhere.

Is there any way that I can reset the printer in Matlab, like delete the printer
settings? Maybe after resetting, let Matlab look for the printer again. This
may solve the problem. What do you think?

Any comment is appreciated. Thank you.

There aren't any printer-specific settings in MATLAB - we query the OS
for the information on what printers are available.

In the print preview case, we don't check whether you're selecting the
default printer (in which case the lpr command without the -P option
could be used); we always provide the -P option to explicitly tell the
OS to use the specific printer.

It looks like something has changed in your print settings during the
Leopard upgrade. Instead of returning the printer NAME ('HP LaserJet
1320') the OS is giving us the IP address. Can you post the printcap
entry for this printer? It should be in the /etc/printcap file.

As a possible workaround, one of my co-workers pointed out that adding
the -H option to the lpr command, telling lpr what server to find the
printer on, may work. Since the OS is giving you the IP address that's
the value you'd set for the -H parameter. To make this change in MATLAB
you'd need to edit the file send.m in the
<matlabroot>/toolbox/matlab/graphics/private directory.
In that file you'll find a section (starting around line 94) that looks
like this:
     if ~isempty( pj.PrinterName )
         %If user specified a printer, add it to the printing command
         if notBSD
           cmdOption = '-d';
         else
           cmdOption = '-P';
         end
         lprcmd = [ lprcmd ' "' cmdOption pj.PrinterName '"' ];
     end
Underneath the line that reads
           cmdOption = '-P';
add the following (above the end statement)
           lprcmd = [ lprcmd ' "-H' pj.PrinterName '"' ];

Note - this isn't a great solution - and it will fail for any printer
for which the OS gives you the real name instead of the IP address...but
it may be sufficient while you're working through the problem.


I also took a quick look at Apple's support site - looking specifically
for IP printer issues with Leopard and found at least one user who
suggests NOT leaving the queue name blank when setting up the printer.
For example, see:
http://discussions.apple.com/thread.jspa?messageID=5683220�
Even though you're only having issues with MATLAB printing, it may be
worth a try to set the queue name explicitly on the printer setup dialog.

Hi Richard,

   Thank you very much for you response. About the queue name problem, I
did an experiment. I set up three printers each with different printing protocol
. I gave each printer a queue name. So, we had

Name Queue Name
------ ------------
HP_IPP HP1320_IPP
HP_LPD HP1320_LPD
HP_Socket (no queue name is required)

Then I restarted my MBP, and opened Matlab. I created a simple plot, and
used both Print Preview and Print button to print out the figure. Here is the
results.

                     under Print Preview use Print button
                    --------------- ---------------
HP_IPP sent w/out error sent w/out error
HP_LPD sent w/out error sent w/out error
HP_Socket sent w/out error sent w/out error

All of the printer settings worked fine when I tried to print the figure, no
error message this time. But, the protocol HP_IPP can't finish the printing,
which had a warning message in the printing job list (can be seen when open
the Print Queue window in Mac). The other two settings worked very well.

So it tuned out that using a queue name was the solution to this problem,
and IPP protocol was not functional in my case. At the end, I delete the IPP
printer setting and use LPD printer setting.

I didn't modify the send.m file, and here is the content of printcap before I
did my experiment. (I hide the IP address)

'-----------------------------------------------
# This file was automatically generated by cupsd(8) from the
# /private/etc/cups/printers.conf file. All changes to this file
# will be lost.
_128_95_xxx_xxx-1|128.95.xxx.xxx
HP:rm=127.0.0.1:rp=_128_95_xxx_xxx-1:
'--------------------------------------------------

Just one question left. I still need to stop by the printer and press the Print
button to let the figure print out. I still have no idea about this one. I didn't
have same situation when I used Mac OSX Tiger. Is it possible to be fixed if I
re-install the Matlab? or is this the problem about X11?

Any comment is appreciated. Thank you very much for your help.


I use Mac OSX Leopard, Matlab 2007a Student version.

I'm glad that setting the print queue name is working for you.

As far as having to go and press the 'print' button on the printer to
get the printout to appear, I don't think reinstalling MATLAB will help.
I suspect it's either a problem with Leopard or with the HP driver
(there seem to be quite a few printing-related issues being discussed on
the Apple Leopard forums).

Hi Richard,

    Thanks a lot for your help. For the problem of pressing the print button, I
found a solution. I reset the printer in my Mac. But this time I let Mac detect
the printer type, not assigning it as HP LaserJet 1320. So I use "Generic
PostScript Printer". Then when I print the figure under Matlab, the figure is
printed without stopping by and pressing the print button. GREAT~

   Just write down my comment to follow up. Thank you.

One more followup for others looking at this thread.

In my investigations here I also found that enabling the
creation of the printcap file in the cups configuration, and
specifying that the printcap file be created in the /etc
directory will enable MATLAB to make the translation between
the printer address/name that is shown in the File->Print
dialog box and the printer queue name that the OS is
expecting. MATLAB has some Mac-only code that does this
translation, but it will only work if the printcap file is
created and in that location (/etc/printcap).

If it's not already configured, edit the cupsd.conf file and
add this line:
Printcap /etc/printcap

I have a similar but not identical problem. I upgraded my
iMac to Leopard (10.5.1) and I am running Matlab R2007b.
I created a plot, then clicked "print" and get the error below.

Any suggestions what to try?
I can print to a file and then via Preview to the printer.

This sounds like the same issue the original poster ran into. There are
2 ways to address it that I'm aware of. The first is a CUPS
configuration setting on the Mac - if there's no /etc/printcap file
created by CUPS, MATLAB's Java-based Print dialog will call the PRINT
command with an invalid printer address, instead of the printer queue
name. This invalid address is not recognized by the operating system.

The CUPS issue can be fixed by adding the following line to the CUPS
configuration file (/etc/cups/cupsd.conf):
   Printcap /etc/printcap
and then restarting the cups process. You may have to login as the root
user to edit this file. Please back up the file before making any changes.

If you are unable to make the above change to the CUPS configuration
file the alternative is to change how the printer is setup in the
operating system. On the Mac's printer browser/print setup dialog do the
following to get MATLAB to recognize the printer:
* set the 'Protocol' field to 'Line Printer Daemon - LPD'
* Set the 'Address' field to the printer host name or address
* leave the 'Queue' name field blank
* **IMPORTANT** IF the printer address field has periods in it, change
the 'Name' field to something that does NOT have any periods
* Close the dialog to save the settings.

You will need to restart MATLAB before these changes take effect.

This sounds like it's the same issue the original poster was
having, which turned out to be caused by a CUPS
configuration issue on the Mac:

There's no /etc/printcap file created by CUPS, which causes
MATLAB's Java-based Print dialog to call the PRINT command
with an invalid printer address, instead of the printer
queue name. This invalid address is not recognized by the
operating system.
 
The issue can be fixed by adding the following line to the
CUPS configuration file (/etc/cups/cupsd.conf):
  Printcap /etc/printcap
and then restarting the cups process. You may have to login
as the root user to edit this file. Please back up the file

Hi, I am getting another similar printing error in Matlab. This time I use a HP
DeskJet 5150 printer and connect it to my MacBook Pro via USB. The Mac can
detect the printer and add it to the list automatically. But when I try to print a
figure under Matlab, it got some errors on printing. The error message
appeared when I click the "Printer" button on the toolbar of a figure.

??? Error using ==> graphics/private/send at 307
Error using ==> graphics/private/send at 129
Problem sending file to output device, system returned error :
lpr: The printer or class was not found.


Error in ==> printdlg>LocalInitFig at 469
  if LocalJavaPrintDlg( Data, Dlgname )

Error in ==> printdlg at 100
   Dlg=LocalInitFig(Data);

??? Error using ==> printdlg(gcbf)
Error using ==> graphics/private/send at 307
Error using ==> graphics/private/send at 129
Problem sending file to output device, system returned error :
lpr: The printer or class was not found.


??? Error while evaluating uipushtool ClickedCallback

Then, I tried to use "Print Preview..." from the menu bar, it came out same
error message. However, if I use command "print" in Matlab command
window, the figure can be printed out by the USB printer (I set this printer as
my default printer in Mac). I am confused about the printing behavior. How
come it is failed when calling a Java-based printing window? I prefer to use
the print window because I can modify the figure (size, scale, etc..). How can I
fix this problem?

Also, I found that in my /etc/cups/cupsd.conf , there is no
Printcap /etc/printcap
Should I add this line? at the very beginning or as the last line?

Any comment is much appreciated. Thanks a lot for help.


I am using MBP, OSX 10.5.1, Matlab Students 2007a.

Yes, you should add that line. It's location in the file isn't too
important as long as it's not contained within a "tagged" section. For
example, NOT within a section like the following:
      <Location />
      Order Deny,Allow
      Deny From All
      Allow From 127.0.0.1
      Allow From 127.0.0.2
      Allow From @LOCAL
      </Location>
Putting it at the end of the file is probably the easiest.


The reason the behavior is different is that the print dialog and print
preview window ALWAYS pass the printer name (using the -P option) to the
print command, even if the chosen printer is the default, and that
printer name is passed along by the print command to the operating
system. When printing from the command line I'm guessing you are not
using the -P parameter to specify the printer, so the operating system
picks the default.

Hi Richard,

Thank you very much. You suggestions solved my problem. Now the printing
is working great. I added the line at the end of cupsd.conf . Thanks again.

Thank you, Richard.
I made the change in "cupsd.conf" as you suggested and now
I can print Matlab graphics correctly.

I have the same problem as 'niner' with Matlab Version 7.1 (R14SP3). I
inserted the line Printcap /etc/printcap after the last line in the file:
cupsd.conf, but I am still getting the error message and no plot.

After you restart cups you also need to restart MATLAB.
Does the /etc/printcap file exist? (note that the filename is case
sensitive - it must be all lowercase)

What does the Mac's print browser/print setup dialog show for the
following fields for the printer you're trying to use?
protocol:
address:
queue:
name:

This worked for me with one caveat--color plots are always printed in black and
white. Is anyone else having this problem? Am I overlooking something
obvious? In the options dialog, I make certain to select the "color" (vs.
"monochrome") option.
