Heya folks, Here at work we just got a brand new HP 8150N laser printer. It's being shared via an NT4 server. I've got the samba client stuff installed and can print to the printer. So far so good, but I'd really like to be able to duplex printed documents. Anyone got any pointers as to where I could start looking? I'm using a notebook running Mandrake 7.0 (XFree86 4+ doesn't seem to support the Trident 9388 video chipset, although 3.3.6 works just fine). It's using lpd for print spooling. I've got a 2.2.14 kernel. Um, any other info needed? I did a quick search on google, which led me to the linuxprinting.org website which has lots of useful information, but only barely mentions output filtering which I gather lets you specify duplex printing, and only appears to with if you're using PDQ as your print spooler. Thanks, Jeff
