I ended up having to load the HP III si driver for both the HP 2100 & 6P printers and so far so good, the only problem I had so far is that one of my reports still had the tag & tag2 fields defined in the frx, which caused the report to go to the printer but required a form feed to be hit on the printer, once I cleared the tag & tag2 fields everything worked fine.

When I did a search for a driver for the HP 2100 TN for windows XP on the HP website it gave me 2 printer drivers to load HP laserjet 2100 PCL 5e or the HP 2100 PCL 6, which driver did you use to get the printer to work ?

Thanks for your help !
