Is this limited to a word processor, email, web browser or ALL?
And what OS?
Finally did you uninstall and reinstall the printer driver?
I have an IBM 4019 Laser printer, It has lost the ability to print highlighted sections of text, It no longer has the 'selected' option in the menu-file-print as it used to, when I highlight a section the page comes out either printed in full or blank.
If I am on line and wish to print a section of text, the option of 'selected' is now available but the page comes out blank when printed.
Any help please?
