Printer Model? Network Connection? Printer Driver is downloaded and installed from Printer Manufacturer OR Apple driver?
Printing from Menu or Script (attached to button or not)?
A new database (from templates?) does the same thing?
A new user created and logged into does the same thing?
Start in Safe Mode (SHIFT key down) and run YASU or ONYX - restart normally shows same problem?
Have you checked it isn't the Print Script? I had this issue where every time I went to print, it did the same thing, it was the print script associated with the print button inside the report that dictated how the report would print.
Check your script.
