HP, and other Printer Manufacturers have their own version of a Universal Printer Driver I have tested the latest HP UPD 5.0.1 and it works with ANY HP printer commercially available- past and present- have tested with 10 year old PSC750 printers all the way up to Eedgelines and latest Colour LaserJet Multifunctions. Xerox make Universal Drivers based on their product families, as do KonicaMinolta and Ricoh The problem here is not that there is no such thing as a univeral driver- there is in Citrix and XenApp but not in a true desktop sense. We all know drivers run on PJL commands and then the breakdown of the rest of the driver files are encapsulated PCL5, PCL6 or PS- I find PCL5 faster, simpler and easier to work with (and create custom drivers). I have supported Printers and MFD's for 5 years and am fully conversant with vendors and manufacturers- and yes simply put you can any HP LaserJet Driver built into wondows and it will work 99% of the time on any printer, but when you want to staple, hole punch and perform page insertions and custom commands or create custom page sizes, then drivers and applications really struggle with UPD's.
