Can you throw data _directly_ at the printer (i.e., *NOT* through lpr/lpd), and will it print? You can't use a simple 'echo Hello, World! >/dev/lp' to find out, because its a fscking 'winprinter'. power everything down, connect the USB cable only, power up the printer first, then the computer. When it has come up, do you have a /dev/usb/lp0 device? Have you created a symlink at /dev/lp that points to /dev/usb/lp0? What happens if you do (as root) where 'testfile.ps' is a simple Postscript doc]: # /usr/local/libexec/ps2hl1250 < testfile.ps >/dev/usb/lp0 how about: # /usr/local/libexec/ps2hl1250 < testfile.ps >/dev/lp For that matter, what does "find /dev -name '*lp*' -ls" show? If any of the names show as symlinks, do an 'ls -l' on the symlink target. I'm guessing that /dev/lp is a 'character device' node, pointing to the parallel port; and when lpd tries tyo print to _that_ -- with only the USB connection, -- it *doesn't*work* (for what is now an 'obvious' reason :) Thanks for your reply. I hate to be such a noob about this but USB and FreeBSD don't ever seem to work right for me. I tried the echo method # echo Hello > /dev/lp /dev/lp: Operation not supported. So I then tried # echo Hello > /dev/ulpt0 and I got an empty prompt until I pressed Ctrl+c to exit. I disconnected everything except the keyboard which is PS2 and the monitor and rebooted the printer and computer allowing the printer to come up first. When I did a directory on the /dev/usb folder this is what shows up: BigDell# ll /dev/usb/ total 0 crw------- 1 root operator 0, 72 Feb 27 07:40 0.1.0 crw------- 1 root operator 0, 76 Feb 27 07:40 0.1.1 crw------- 1 root operator 0, 94 Feb 27 02:40 0.2.0 crw------- 1 root operator 0, 96 Feb 27 02:40 0.2.1 crw------- 1 root operator 0, 97 Feb 27 02:40 0.2.2 crw------- 1 root operator 0, 87 Feb 27 02:40 0.3.0 crw------- 1 root operator 0, 89 Feb 27 02:40 0.3.1 crw------- 1 root operator 0, 100 Feb 27 02:40 0.3.2 crw------- 1 root operator 0, 74 Feb 27 07:40 1.1.0 crw------- 1 root operator 0, 77 Feb 27 07:40 1.1.1 I'm not so sure this is what we call a Windows printer. Maybe I'm off base there but by that if you mean it's not a real printer and relies on Windows to do most of it's work then I can't say. What I can say is that this printer worked perfect under FreeBSD with the parallel connection and a simple setup with apsfilter to use the HL-1250 drivers. And it did print a few things yesterday from the command line using the parallel connection. I sent some postscript files through the ifhp filter from the /usr/share/examples/printing/ folder and just changed the device from the DJ500 to HL1250. BigDell# find /dev -name '*lp*' -ls 45 0 crw------- 1 root wheel 0, 45 Feb 27 07:40 /dev/lpt0 46 0 crw------- 1 root wheel 0, 46 Feb 27 07:40 /dev/lpt0.ctl 98 0 crw-r--r-- 1 root operator 0, 98 Feb 27 07:49 /dev/ulpt0 99 0 crw-r--r-- 1 root operator 0, 99 Feb 27 02:40 /dev/unlpt0 No symlinks found in this search. BigDell# /usr/local/libexec/ifhp < /tmp/ntpdate.ps > /dev/lp /dev/lp: Operation not supported. BigDell# /usr/local/libexec/ifhp < /tmp/ntpdate.ps > /dev/ulpt0 This last one gives me an empty prompt waiting for more input I guess until I press Ctrl+c to exit. I wonder how this would play out on a 7.2-STABLE machine. I have one handy and will test it out next. I've been told that USB was completely rebuilt from 7.x to 8.x. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
