Hi Jeremy,
Have you been able to print successfully to your Samsung SCX-4200
printer via ulpt0 directly (without using samba)?
The same happens whether I use lptest against the device or samba with
the appropriate drivers: the laser printer starts to make some noise and
warms up like it's going to print something, and doesn't print anything
in the end. I tried both, /dev/ulpt0 and /dev/ulpn0.
Before, I didn't see I was having those in the logs,
ulpt0: offline
ulpt0: output error
I've also seen this error below on another occasion, I cannot reproduce
it. It was probably caused by my attempt to reconnect the USB cable
physically.
uhub0: device problem, disabling port 4
Anyway I've disabled ACPI at boot time and I don't get any of those for
now anymore, while the main issue remains.
I think it uses a proprietary format. Some open source driver is at
http://splix.ap2c.org/ but for CUPS. I didn't look at it, but maybe you
can make that work so you can test locally.
Anyways, I have had ongoing problems trying to print via some ulpt0
printers. There are a few threads about it. I do have good success
using a Brother HL 5150D Postscript printer over ulpt0 using lpd for
several years now. You may find that using a printer with a
non-proprietary format may be easier.
Well I was using good old HP Laserjet 4L before, which I think, aren't
postscript either, and it was still printing the text I sent to the
device directly (even though there was some indentation issues, the
drivers being mandatory to print other documents). My point being, is
it truly mandatory for the printer to be postscript compatible to be
able to do that (lptest > /dev/ulp{t,n}0) or LPD/samba with a raw
printacap entry?
Thanks
Pierre-Philipp
