Hi, all.

My printing's not working. I've got cups-1.4.8-r1 installed.

If I attempt to print from (say) Mozilla, everything appears to go fine
up to the actual printing. I do

# lpq

, then I get this:

ML-1450 is ready and printing
Rank Owner Job File(s) Total Size
active acm 44 Lernen im Internet - Anmeldung 94208 bytes

.

However the printer isn't actually printing. I know there's nothing
wrong with the printer or USB cable as such, since I can do

$ echo printing^L > /dev/lp0

, and a page with "printing" on it comes out of my printer.

Any suggestions?

Have you checked the cups setup - http://localhost:631 - and looked at all
the setup settings and the Jobs queue? Sounds like a driver issue to me, but
I always use HP printers, and hplip takes care of the drivers. I'm not
familiar with the drivers for Samsung products.

Perhaps someone will come along who has that printer that can assist you.
Also you might ask on freenode IRC, channel #gentoo. That is a very helpful
resource. Good luck!

Have you tried deleting the cups printers using the localhost:631 cups
server? I've had so many obscure printing problems after updating the
cups package, I just routinely delete and recreate the printers before
I even try to print something. Usually fixes my printing problems.

The backend driver might be failing. See cups error log.

I have done the same thing in the past. It's amazing how a delete and
re-add can fix things.

I use HP printers to tho.

Also, reconfigure the driver in http://localhost:631 because sometimes drivers
change and your cups set up may still be pointing to the old driver.

Hello, Walt.

OK, I tried that (though it turns out it wasn't the problem, see below).
I'm glad I wrote down my about-to-be-deleted config first. localhost:631
has got to be the cruddiest GUI configurer around. I think I had to
describe my (USB connected) printer as "scsi", and then a little later
had to enter a "NAME", without any indication being given of whose name.
Luckily, I have enough experience to guess correctly, 'cause there's no
help on these things. How I hate cups!

My actual problem was that my printer is on /dev/lp0, generated by mdev.
When I switched back to a udev system, the printer's on /dev/usblp0
(which is a symlink to /dev/usb/lp0).

There doesn't seem to be anything in any cups config file to specify the
device to print to. The nearest thing to a config item is

DeviceURI usb://Samsung/ML-1450

in /etc/printers.conf. I don't know where "usb://" is defined - Firefox
rejects it straight off. I don't know how this URI is converted to
/dev/usblp0, but it seems to be hard coded in effect.

So, can I configure "usb://Samsung/ML-1450" as /dev/lp0?

I think you mean /etc/cups/printers.conf ?

In your printers.conf try something like:

DeviceURI usb:/dev/usb/lp0

or

DeviceURI usb:/dev/usblp0


For parallel connection it would be something like:

DeviceURI parallel:/dev/lp0


Don't forget to restart cups.

An an upgrade to anything that want to modify *.config,

I so to the dir and save about-2-be-deleted version
of all config files. For example in /etc/cups/

printers.conf
printers.conf.31aug11
printers.conf.5dec10
printers.conf.6jun2011
printers.conf.orig (original)

I could use the optional names during the updates,
but those names are non sensical to me.

It's saved my bacon on too many occasions, as cups
it not the only brain_dead software and keeping
config records that can be date correlated, helps
on a variety of issues. Occasionally I prune the
files.... I asways use hplip with HP printers.

I think dispatch.conf does this automatically. I use it here and it has
backups of my config files. Of course, I also keep a backups manually
from time to time. Usually if I have a good long uptime and can reboot
with no errors, I make a new backup. I have never used dispatch.conf to
recover a config tho.

OP, you may want to check into this if you do have issues with updates.
It may be handy and automatic too.
