[gentoo-user] cannot print after changing CUPS printer

[gentoo-user] cannot print after changing CUPS printer

[Michael [Plouj] Ploujnikov]

I used to print to a LAN CUPS printer at
lanmachine:631/printers/printername until I recently took that
(parallel port printer) and hooked it up to lp0 on my local machine.
Since then I cannot seem to print from any local application nor does
lpstat show any printers:

currently this is what I see:
$ lpstat
lpstat: Unable to connect to server: No route to host

I think it's still trying to connect to the old CUPS printer on a
different machine

however:
$ lpstat -h localhost -t
scheduler is running
system default destination: gray-deskjet
device for gray-deskjet: parallel:/dev/lp0
device for pdfprt: cups-pdf:/
gray-deskjet accepting requests since Jan 01 00:00
pdfprt accepting requests since Jan 01 00:00
printer gray-deskjet is idle.  enabled since Jan 01 00:00
printer pdfprt is idle.  enabled since Jan 01 00:00

The only way I can print to my local printer is if I select "print
test page" from the CUPS web interface so I know the printer is
working.
The funny thing is that I can also print to this local printer from
other machines - Linux and Windows via IPP/CUPS.

Assuming that you have started cupsd (well, if you can print a test
page then you definitely have cupsd running ;-) what does lpstat -d
show?

$ lpstat -d

Yes, if course, I (re)started cupsd multiple times.

You could try to use the Cups GUI and stop/delete the pdfprt printer.
Athough I have set up my PC for three different connections to a
printer, only one of them is active and of course set up as the
default.  Another thing, use cancel to delete any queued jobs first
just in case.

None of that seemed to help either. On a side note, I recall that I
can't print to the local "pdfprinter" as well  - other than printing a
test page.

Also, note that lpstat returns the same for root and normal user.

Did you by any chance change your /etc/cups/cupsd.conf file settings
from the default?  How is your pdfprint connected to the PC?  If they
are both connected via your parallel port, have you configured it
correctly in your kernel?  Sorry for stating the obvious but the error
seems to point to an incorrect route (path) to the printer.  have you
tried via USB?

please ignore pdfprint for the sake of this thread. I am only
concerned with the other printer -  gray-deskjet: parallel:/dev/lp0

There is only one parallel port printer attached to my system, that is
the printer in question here:
gray-deskjet: parallel:/dev/lp0
Yes, I compiled the kernel properly. That is how other machines on my
LAN can print to this printer, and I can print a test page using CUPS
web interface.

This printer does not have a USB connection, unfortunately.
The printer model is HP 710c, for your information.

I'm sorry if I have missed it but have you looked in your cups error
log for any messages.  Also set your log level to debug and restart
cups to get more detailed messages.

The problem is that my print jobs don't even reach my local cups server!

Here is an example:
$ enscript --verbose=3 todo
AFM: scanning path...
AFM: reading font map "/usr/share/enscript/afm/font.map"
AFM: font mapping: AvantGarde-Demi -> /usr/share/enscript/afm/agd
...
... font crap removed to conserve space
...
AFM: font mapping: ZapfDingbats -> /usr/share/enscript/afm/zd
reading AFM info for font "Courier"
file_lookup(): /usr/share/enscript/enscript.pro #t
file_lookup(): /usr/share/enscript/88591.enc    #t
file_lookup(): /usr/share/enscript/simple.hdr   #t
%Format: fmodstr $D{%a %b %d %H:%M:%S %Y}
%Format: pagenumstr $V$%
processing file "todo"...
lpr: error - scheduler not responding!
[ 1 pages * 1 copy ] sent to printer

I think there is some kind of a magical hidden setting that still
makes lpr/cups think that my printer server is on a different machine
(namely lanmachine:631/printers/printername) instead of localhost.

I would try commenting out the line with LOCAL above and check or add
the following:
=====================
User lp
Group lp

Listen 127.0.0.1:631

Browsing Off

SystemGroup lp

<Location />
Order Deny,Allow
Deny From All
Allow From 127.0.0.1
</Location>

<Location /admin>

AuthType Basic
AuthClass System

Order Deny,Allow
Deny From All
Allow From 127.0.0.1

</Location>
=====================

If the above setting works you can start tightening things further,
including encryption, etc. if this machine is exposed to the elements
of nature.  :-)

My config is already almost exactly like that, except that my config
does not specify:
Listen 127.0.0.1:631

and this was enabled to allow other local CUPS servers (on a laptop
computer) to print to my printer:

BrowseAddress @LOCAL

I tried adding "Listen 127.0.0.1:631" but cups actually refused to
start because it was "
Unable to bind socket for address 00000000:631 - Address already in use."

my CUPS automatically listens on: 0.0.0.0:631

127.0.0.1 is localhost (loopback) and is needed for your computer to
be able to connect to its own cupsd and thus be able to print.

I assume you have replaced @LOCAL with @192.168.0.1/24 or whatever the
local address is?

OK, but 0.0.0.0 is *every* address in the universe, not the localhost
address.  Add localhost:631 it should do the same job like 127.0.0.1.

Finally, check that the Deny/Allow is set to Deny all and Allow
127.0.0.1.  Otherwise I've run out of ideas . . .

Actually, according to the comments in the conf file, it should be
exactly "BrowseAddress @LOCAL" if I want cups to listen to local
devices only. Anyways, I tried to set it to my network and it didn't
help. It really is for other cups servers to be able to communicate
with mine.

I set it to "listen localhost:631" and still nothing

 Yup, my deny/allow rules are Gentoo's default, except that I added a
rule to allow for my LAN pcs to access this server.

I think the problem is not in the cups config/server, but in the lp
side of things. I think it is somehow trying to connect to the wrong
server.

OK lets think through this once more.  Your original $ lpstat -h
localhost -t output although it shows  your gray-deskjet as the
default destination, it does not show that the other printer is
paused.

Try again to manually set the default printer (for all users) and see
if it picks it up:

# lpoptions -d gray-deskjet

May be worth re-naming ~/.lpoptions file if it exists to make sure
that only the /etc/cups/lpoptions are read by lp on each occasion.

Then stop the pdfprt (not sure how you do this from the command line,
I use the GUI).  Check that pdfprt is stopped, gray-deskjet is idle
accepting jobs and is the default printer using $ lpststat -h
localhost -t.  Then try to send something to the printer using lp,
e.g. lp foo.txt.

My guess is that for some reason your pdfprt is being picked up and
its address cups-pdf:/ is not correct?

I already setup pdfprt  to be paused.
Then I checked for ~/.lpoptions as a normal user, and didn't find it.
It appeared that /etc/cups/lpoptions still pointed to the old printer
(neither pdfprt, nor gray-deskjet).
So I tried to do:
# lpoptions -d gray-deskjet
lpoptions: Unknown printer or class!

Then I tried 'lpoptions -h localhost -d gray-deskjet' and it worked.
This changed the default printer in /etc/cups/lpoptions.

However, lpstat  still says it cannot connect to server, and for
example enscripting a text file fails as well:
$ enscript todo
lpr: error - scheduler not responding!
[ 1 pages * 1 copy ] sent to printer

$ enscript -P gray-deskjet todo
lpr: error - unable to print file: server-error-service-unavailable
[ 1 pages * 1 copy ] sent to gray-deskjet

$ enscript -d gray-deskjet todo
lpr: error - unable to print file: server-error-service-unavailable
[ 1 pages * 1 copy ] sent to gray-deskjet

In fact, I just deleted pdfprt, and the situation still has not
changed (ever after restarting cupsd).


I just ran lpstat with strace, and I notices something that I
suspected all along, it tries to connect to my old print server:

connect(4, {sa_family=AF_INET, sin_port=htons(631),
sin_addr=inet_addr("10.1.1.4")}, 16) = -1 EHOSTUNREACH (No route to
host)

I hope no-one minds if attach the whole output from strace here.
