I have been reading Konrad's posts and the replies to the mailing list regarding getting his HP printer to work. I also have an HP 656C USB printer. I am running 4.7-Release. Like Konrad the kernel does see the printer when it plugged in: Apr 6 11:06:05 freshaire /kernel: ulpt0: HEWLETT-PACKARD DESKJET 656C, rev 1.10/1.10, addr 2, iclass 7/1 Now here comes the interesting part since I figured it would be a good idea to start debugging this with a simple setup (no printer spooler, etc.) I have tried to do echo "hello there" > /dev/ulpt0 and nothing happens. It takes about 30 seconds before the command ends. I have tried this on another system with FreeBSD and the 656C printer and get the same results. If I try the echo using Linux the printer works just fine. I.e. a page is printed with "hello there". I then verified I had the proper support in the kernel: kldstat -v | egrep 'usb|lpt' 14 ppbus/lpt 121 ohci/usb 122 uhci/usb 127 uhub/ulpt 130 usb/uhub The code is compiled into the kernel (not a module) Any suggestions as to how to proceed? Are there any driver debug options that can be enabled either for USB or the printer code? Thanks, Marc -- Marc Wiz marc@wiz.com Yes, that really is my last name.
