Print an image in Matlab GUI

How do you print an image from a printer in Matlab GUI? I get an error using the code below. Please help me.

   Undefined function or variable 'smapleimage'.

   smapleimage = imread('image.png');
   printdlg(handles.smapleimage)

I guess it should be

smapleimage = imread('image.png');
printdlg(smapleimage)

[Eric Letsolo]

it returns an error message. Error using cellfun Non-scalar in Uniform output, at index 1, output 1. Set 'UniformOutput' to false.

This error does not come from the two lines you showed here. Please show the entire error message, and the code where it came from.

This is the code

function Print_Callback(hObject, eventdata, handles)
smapleimage = imread('d.png');
printdlg(smapleimage)

Error using cellfun
Non-scalar in Uniform output, at index 1, output 1.
Set 'UniformOutput' to false.
Error in printdlg (line 13)
idx = cellfun(@(X) any(ishghandle(X,'figure')), varargin);

Ok, printdlg only accepts figure windows. Try this:

hFig = figure();
smapleimage = imread('image.png');
imshow(smapleimage)
printdlg(hFig)

[Eric Letsolo]

I can print a figure using printdlg(handles.Fig) Is it possible to print out an image from Matlab GUI
