Hello,
I've successfully set up many printers, using cups and HPLIP before. I prefer to use CUPS. So I cannot find an explicit listing for this new model HP printer: "OfficeJet Pro 8500"; so I'm using this driver: HP OfficeJet Pro 1150C. Everything works, admin from localhost:631 for CUPS; HP printer admin from the embedded web server (very cool). It has a multitude of settings, but no duplex setting. I'm trying to avoid using the HP disc on an XP system for admin....... The HP literature clearly states this is a duplex printer. I can copy both sides of a letter size document to a single page, just using the menu on the printer. So I can see that it duplexes. So I'm concluding (for now) that the problem is the CUPS (best/closest I could choose) driver does not support Duplex printing. Does anyone know of an HP OfficeJet driver that supports duplex printing? I have not been successful in finding a CUPS drivers specifically for this printer: HP OfficeJet Pro (A909g) and I really do not want to use HPLIP. CUPS-1.4.2-r1 is installed. Any suggestions are most welcome. James
