Printer of Hearts

When I boot my computer my printer(Lexmark Optra E312L – parrallel) prints out 2 little hearts in the upper left of the sheet. The drivers are the latest. It’s plugged directly into the computer. No network printers are mapped using LPT 1. And I installed the same printer on another PC and it doesn’t have the same issues.
Any ideas out there? Thanks and have a good one!
