I've been printing photos and creating PDF's this way for years, but all of a sudden it's not working. I'm having the same problem for both.
Generally I open up my 300 dpi images in photoshop, then open a new 8.5x11 300 dpi file, drag my photos or images into it and print the whole page. But now, when I open my 8.5x11 file and drag my images in they're super small on my new canvas.
If I just open a photo and ctrl-p to print it prints to the correct size... so it's the 8.5x11 image that's the problem. If I create the file with pixels instead (2550x3300) it's still tiny.
Does anyone know why this is and how I can fix it? I need to use photoshop for work, so this needs to work. Please.
Are you sure the resolution of both files is identical (and not one ppi and the other ppcm)?
