I have the above mentioned USB printer. It requires the foo2zjs
driver which I've successfully compiled from the foo2zjs web site
(following the OpenBSD instructions). Unlike most printers, the
HPLJ1018 does not have "persistent" firmware. Instead, its firmware
(the file 'sihp1018.dl') must be uploaded to it every time it is
physically powered on.
When I power up the HPLJ1018 and plug it in to one of my PC's USB
ports, dmesg shows:
ulpt0 at uhub0 port 2 configuration 1 interface 0 "Hewlett-Packard
HP LaserJet 1018" rev 2.00/1.00 addr 2
ulpt0: using bi-directional mode
However, when I try:
$ cat hp1018.dl > /dev/ulpt0
The terminal cursor just hangs. The same thing happens when I try it
as root. Eventually, things time out and I get the response:
ksh: cannot create /dev/ulpt0: Device busy
I've tried disabling ulpt0 at boot:
boot> -c
disable ulpt
quit
this is correct
and then:
# sihp1018.dl > /dev/ugen0
use cat sihp1018.dl >/dev/ugen0
and of course configure your printcap to print to ugen0.
it works, we use ton's of these printers (I think even the same
model)
but it still does not appear to load properly - the cursor just goes
back to # shortly thereafter and nothing happens. Anything I print
disappears into a black hole. When I try things in linux the
printer emits a few noises and the print head moves and subsequent
printing works without a hitch.
I fear I'm doing something wrong in uploading the firmware (am I
missing steps?). I'm quite new to OpenBSD and am having trouble
finding guidance on how to upload firmware to peripheral devices.
Can anyone help me out?
Kind regards
Ooops. My mistake. The missing 'cat' was a typo. Sry.
I'm using CUPS so IIRC /etc/printcap is overwritten by CUPS and that I
should edit /etc/cups/printers.conf instead. (Is that correct?) If I
do this, and change the line:
DeviceURI usb:/dev/ulpt0
to:
DeviceURI usb:/dev/ugen0
I get the error message "Unable to open USB device "usb:/dev/ugen0":
Permission denied". I can only see '_cups' in /etc/group and when I
change the permissions of /dev/ugen0 to 646 I still get this
permission error.
Why would you have permission 646? Try firstly the most naive approach
by changing permissions
as
# chmod 0666 /dev/ugen*
# chmod 0666 /dev/usb*
then once you get everything working adjust the group ownership to _cups
and restrict permissions to something like 0664 or even more restrictive.
I'm stumped.
