I have been tinkering around with CUPS for the last few days trying to get print sharing to work. Did not have problems printing documents from this desktop. When I went to print a document I found that my printer was not listed. Using localhost:631/admin shows lists the printer, but when I open System->Administration->Printing, the window opens (after a few seconds), grays out, and a blank display. The option to add a printer is grayed out.

In terminal window:
lpstat -v
lpstat: Connection timed out
lpinfo -v
lpinfo: Connection timed out

What happened to the parallel port?

Thanks, GeoK

Have you got the parallel port modules loaded? To find out, open a konsole, run the command 'lsmod | grep ppdev' and see if ppdev, parport_pc and parport are listed. If not, try loading them.

Only other thing I can think of is some how cups has got hosed up. Possibly restart cups?

Thank you for the reply.

This was my outuput for lsmod | grep ppdev:
ppdev 5259 0
parport 32635 3 ppdev,parport_pc,lp

I failed to mention that after the problem began, I removed cups and then installed cups again. Just to be thorough I did execute /etc/init.d/cups stop and /etc/init.d/cups start, but no improvement. When I try to print from my web browser, the entire window grays out and becomes unresponsive until the print window appears.

Did you re-install the printer after the cups re-install? Did it ever print after the re-install?

At localhost:631/admin I was able to install my printer, but it still will not print. The web browser grays out as described earlier, and lpstat and lpinfo still times out.

This sounds like some kind of a permission issue. What do you see if you go to System-->Admin-->Printing? There should be icon(s) there, one for each printer. Right click on the printer, Properties, and look at Policies, and Access Controls. Make sure your user has access.

System->Administration-> Printing takes about 20 seconds to open. Once it finally opens there are no printers displayed. When I select Server->New both Printer and Class are grayed out. If I select Server->Connect then the Connect to CUPS server appears. The only available CUPS Server is PrinterHost. If I select Connect then a CUPS server error tells me that "There was an error during the CUPS operation: 'failed to connect to server'."

What do you see in /dev for parport0 ? Her is what it looks like on my system.

The group is lp. Is parport0, or what ever parport# you have set to rw for the group?

Yes, the group permission is rw

ls -l parport?
crw-rw---- 1 root lp 99, 0 2011-02-02 15:12 parport0

I'm just about of ideas.

Have you at any time made changes to /etc/cupsd.conf file?

This is the file to configure cups. As far as I know, lpstat talks to cups to display status information. I'm wondering if there is a problem in the config file.

Could you also make sure cupsd is running? the command 'ps aux | grep cupsd' should tell you if cupsd is running.

Result for ps aux | grep cupsd:
Yes I have made changes to the /etc/cupsd.conf file. This is the only section that I made changes:

LogLevel warn
MaxLogSize 1m
SystemGroup lpadmin
# Allow remote access
Port 631
Listen /var/run/cups/cups.sock
Listen 127.0.0.1
# Enable printer sharing and shared printers.

The places you have cupsd listening are different to mine. Since this is part of the problem, lpstat not talking to the daemon, try changing the listening entries to match mine. Restart cups, and see what happens.

Here is the way mine is set up.

I'm not listening on 127.0.0.1 at all.

I commented out the line for listening to 127.0.0.1 and and changed the Port 631 to Listen *:631, but unfortunately no change.

Thank you for your time. GeoK

If you run a 'ping localhost' do you get a response like this -

Yes, just like that:
