I power-cycled the printer, unplugged the USB cable, restarted hplip and cups, and plugged the cable back in. When I went back into the CUPS web interface, I saw that the printer was listed about four times on the initial page under "new printers found". I installed it as Device URI: usb://HP/color%20LaserJet%202550%20series This prints just fine but the hp-* tools don't recognize it, of course. The other lists that specify the hp: CUPS backend (those that actually use hplip) still won't print. I can, however, run hp-toolbox and view all of the statistics and whatnot for the printer if this printer-that-won't-print is set up under CUPS. So it appears that I can access all of the functions of this printer by having it listed twice. Once as a usb: device to actually print with, and once as a hp: device to view status and clean it and so on. This isn't the greatest solution, though. -- MELVILLE THEATRE ~ Melville Sask ~ http://theatre.sasktelwebsite.net
