now I understand, thanks for the clarification. 2.2.5-2 changes nothing
for me.

This bug is against cups 2.2.4-1. Perhaps I was unclear. I suggest
testing the behaviour of 'lpstat -a' and the commands Samuel used
with unstable's cups 2.2.5-2.

I do not have a ~/.cups folder nor any lpoptions
(in /etc/cups/lpoptions or somewhere else) nor any PRINTER
environment variables set. Only the afore mentioned entry
in /etc/cups/client.conf. So I do not see how 877888 could relate to the
problem and I do not see, what I could try from the suggestions in that
bug.

Samuel and Julian, please take a look at #877888 and let us know if it
fixes things.

Hi,

similar/same(?) issue here:
$ lpstat -a
lpstat: Dienst nicht verfügbar
(translation: lpstat: Service not available)

The remote print server is configured via /etc/cups/client.conf
$ cat /etc/cups/client.conf
ServerName hostname-of-server/version=1.1

Downgrading to the version in stable makes me see all printers again
and able to print.

Cheers,
Julian

I had read that bug, and thus removed my .cups/lpoptions file already,
with the same issue.  I don't think the two bugs are related.

I was just about to post in reply to M G Berberich's mail to #870463
when this one arrived. My suggestion was (and still is) that the 
~/.cups/lpoptions be moved and the PRINTER (or LPDEST) environment
variable be set instead. (M G Berberich has been CC'ed).

pcl is a local print queue set to print to a file.

With 'lpstat -d' I get

  lpstat: error - PRINTER environment variable names non-existent destination 
"pcl".

'lp /etc/nsswitch' gives

  lp: Error - scheduler not responding.

Regards,

Brian.

Bug#873606: cups: 2.2.4 stopped being able to interact with our cups server

[Samuel Thibault]

Package: cups
Version: 2.2.4-1
Severity: important

Hello,

Since the upgrade to 2.2.4-1 (more precisely, it is the upgrade of
libcups2 which breaks things), I'm not able to print any more:

[with 2.2.3-2]
$ lpq
print2me is ready
no entries

[with 2.2.4-1]
$ lpq
lpq: Error - PRINTER environment variable names non-existent destination 
"print2me".
$ lpr
/usr/bin/lpr: Error - scheduler not responding.
$ lp
lp: Error - scheduler not responding.

but oddly enough:
$ lpstat -a
print2me accepting requests since mar. 29 août 2017 14:13:48 CEST


Anyway, I had to downgrade to 2.2.3-2 to get printing back working.


I'm using
$CUPS_SERVER=cups.bordeaux.inria.fr
$CUPS_USER=thibault
$PRINTER=print2me

The server shows: CUPS 1.6.3

Description: File d'attente Follow Me
   Location: Follow Me BSO
 Driver: TOSHIBA ColorMFP (color, 2-sided printing)
 Connection: lpd://193.50.111.138/secure
   Defaults: job-sheets=none, none media=na_letter_8.5x11in 
sides=two-sided-long-edge


I have attached the TCP sessions of each version. It seems like the cups
client does not send $PRINTER to the server at all, thus "No default
printer" beign returned.
