Printing FMS purchase orders

[Jobos]

I’ve got an XP machine which is refusing to print purchase orders to a HP 2600n printer, however it will print to a HP 3600n in the next room. I’ve installed the latest drivers for the 2600n but it still won’t print from the XP machine. Printing orders from the 2000 server or a Vista machine to the 2600n works fine.
