[cups] Debian Stretch strange printer problem

[arne]

Hi,

My printer suddenly didn't show up in the Print Window
of Libre Office, Firefox and a lot of other programs.

I can however Print to File in pdf or ps and print those with lpr
from the command line.

The printer shows up in CUPS page and I can print the test page from
CUPS.

I did try reinstalling its driver software, removed and added the
printer with CUPS again.


It is a WiFi Brother HL-L2340DW laserprinter.

>From another system, also with Debian Stretch amd64 everything works
fine.

some data I collected, I can not find any error there:

To find the available printers, at a terminal type:
# lpstat -p -d

printer HLL2340D is idle.  enabled since Sun 14 Jan 2018 07:56:30 PM CET
printer PDF is idle.  enabled since Sun 14 Jan 2018 04:39:50 PM CET

Then to pick one as the default lpd printer, type:
# lpoptions -d HLL2340D
copies=1 device-uri=socket://192.168.2.7 finishings=3

marker-colors=#000000,none marker-levels=-1,97 marker-names='Black\ Tone


Then type lpq to see if the printer you selected is now the default:
# lpq
HLL2340D is ready
no entries

To show all printers that accept jobs:
# lpstat -a
