Solve : USB to IRDA converter connection to mobile printer?

1.	Solve : USB to IRDA converter connection to mobile printer?
Answer» I PURCHASED a used legacy Pentax Pocketjet (I) printer. The only data communication with it is via IR. It functioned properly for the previous owner. None of my computers had IR, so I purchased an IR USB bridge. I have installed the requisite drivers for printer and bridge, but cannot get the printer to work. Computer(s) keep telling "This document FAILED to print." I have tried two computers and have been futzing with it all day. Printer driver used (per printer manual) is HP laserjet IIP, OS is XP. Bridge is http://www.pccables.com/70622.html. I am thinking that I am not identifying the proper printer port, though I have tried USB, LPT, COM, IR options. (IR beams are within one foot and lined up) Can anyone help? All HARDWARE is detected and installed under device MANAGER?
