Printing .pdf files, what is showing on both the screen and the print preview is not what gets printed.
I have Adobe Acrobat Standard DC installed on Windows 10 printing to a Lexmark printer. When I print .pdf files sent in by my clients regularly what is showing on both the screen and the print preview is not what gets printed. Often large amounts of the page are just blank or it prints random words. On multi-page documents it might only print the first page and then a third of the next page, yet shows them all in the print preview. Very frustrating. How do I fix this please ?
