Dynamics GP - Can print to screen, but when printing to printer, nothing prints, with no error message

When a batch is posted, 3 or 4 reports may print to screen.
The way GP processes these tasks is as follows

• Print Report1 to screen
• Print Report2 to screen
• Print Report3 to screen
• Print Report4 to screen
• Complete Posting
• Submit print requests to printer

GP will not actually submit the print jobs to the printer until all of the "print to screen"s have been processed

If this is not the issue then try
Backup Reports.dic first
After ruling out printer and connectivity issues, test printing with a new dictionary.

If this works, dictionary is corrupted.
Remove old dictionary, reimport all customizations
