Only problem at printing using printer

qrCodeImagePath = 'qr.png';

% Read the QR code image
qrCodeImage = imread(qrCodeImagePath);

% Display the QR code image
imshow(qrCodeImage);
title('QR code');

% Adjust figure size to paper size
set(gcf,'PaperPositionMode','auto');

% Set paper orientation to landscape
set(gcf,'PaperOrientation','landscape');

% Specify printer
printerName = '-PTP518G';

% Print the QR code image to the printer
print(printerName, '-r300')

This is the Matlab script all is ok just at the printing part then popped out the warning below.

Warning: The figure is too large for the page and will be cut off. Resize the figure, adjust the output size by setting the figure's PaperPosition property, use the 'print'

command with either the '-bestfit' or '-fillpage' options, or use the 'Best fit' or 'Fill page' options on the 'Print Preview' window.

The qr.png image that you displayed occupies more than about 8 inches wide when displayed. When you ask to print that, the settings you have are that it should keep that screen width -- but since that is wider than the size of the printer paper, that it should deal with that by cutting off part of the image.

If you want the image to be automatically rescaled to fit the size of the paper, then use

print(printerName, '-r300', '-bestfit')

what's the difference between bestfit and fillpage.I tried bestfit before but then the printer sound like stucking and unable to print out anything.

[Walter Roberson]

"bestfit" preserves aspect ratio; "fillpage" does not preserve aspect ratio.
