MATLAB: Error/warning occurs while saving the axes as .jpeg file in GUI MATLAB

axesjpegmatlab guisave

Hi,
I have referred this examples to save the current result as .jpeg on axes in GUI MATLAB. It save the current result of the axes in the current file, however it appeared some error/warning on the command window:
This is the code that I used in the push button callback function:
% --- Executes on button press in save_pushbutton.
function save_pushbutton_Callback(hObject, eventdata, handles)
% hObject    handle to save_pushbutton (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
newfig1 = figure('Visible','off'); 
copyobj(handles.image_axes, newfig1);
new = print('-djpeg',newfig1);
saveDataName = fullfile(path1,filename1); 
saveas(new,saveDataName,'jpeg');
and the error is:
Error while evaluating uicontrol Callback
Warning: Files produced by the 'jpeg' driver cannot be sent to printer.
File saved to disk under name 'figure20.jpg'.

Thus, could anybody help me to overcome the problem?Tq

Best Answer

You should either use print or saveas, not both together.
The only time print() can give an output is if you pass it the '-RGBImage' argument (only) in which case it is to return an RGB array that is a copy of the current figure.
