I have a similiar "issue" with a HP LaserJet 4 Plus, which is capable of 12ppm. It's connected to my network using a JetDirect card on 100mbit switch, so speed of the interface shouldn't be an issue. I'm using the hpijs drivers currently. I would also agree that it seems to print more slowly than in Windows. My impression is that the LaserJet 4 is quite an old printer and has a relatively slow processor and therefore seems to spend quite a long time processing each page. I don't know for sure but I think it's just simply that it has to do more processing for UNIX print jobs. E.g. on WIndows it looks something like this: Application > PCL -> Printer On FreeBSD, mine does something like this: Application -> PostScript -> PCL -> Printer I was wondering if the PCL generated from PostScript was rather more complicated than that generated by the Windows driver and therefore required more processing. also take a look at (misleadingly-named) www.linuxprinting.org. They reccommend the use of the pxlmono driver, and say that it's much faster than others: http://www.linuxprinting.org/show_printer.cgi?recnum=HP-LaserJet_2100 Cheers, Chris Howells
