Canon CCP stopped printing recently

My Canon LBP3300 network printer has been working well for a couple of years and survived Fedora upgrades along the way. Some time in the last few days, it has stopped printing. I would like some help working out what went wrong and how to fix it.

I am now on Fedora 32 and all updates are applied.

I am not sure when this occurred because I don’t print that often, but print jobs get submitted OK and seem to work including the 2 popup notifications. I cannot do a test print either.

I have removed and re-installed / configured the canon drivers with no change.

Here is the setup:-
I am using Canon drivers as follows:


  • cndrvcups-common-3.21-x.x86_64.rpm
  • cndrvcups-capt-2.71-1.x86_64.rpm
[graham@gm-ws1 ~]$ sudo systemctl status ccpd

Here are the CLI commands I use to set it up:

$ sudo lpadmin -p LBP3300 -m CNCUPSLBP3300CAPTK.ppd -v ccp://localhost:59687 -E

$ sudo ccpdadmin -p LBP3300 -o net:

$ sudo cat /etc/cups/printers.conf

So I set the cups log level to debug2 and this is what I get in journalctl:

Nov 03 14:17:26 gm-ws1 cupsd[148860]: [Client 310] cupsdReadClient: error=0, used=0, state=HTTP_STATE_WAITING, data_encoding=HTTP_ENCODING_LENGTH, data_remaining=0, request=(nil)(), file=-1
Nov 03 14:17:26 gm-ws1 cupsd[148860]: [Client 310] HTTP_STATE_WAITING Closing for error 32 (Broken pipe)
Nov 03 14:17:26 gm-ws1 cupsd[148860]: [Client 310] Closing connection.

I have looked at the RemoteUI on the printer and there are no failed print jobs in the log. It does however show 2 print jobs from windows computers.

So Win7 with canon CAPT drivers installed works just fine.

There is no restrictions on IP address that would stop the print jobs. A notebook running Fedora 32 runs win7 in a virtual machine. Win7 printed on that PC but not from Fedora.

I am not sure what to test now.

Any help appreciated.

I don’t know why you thought that removing, reinstalling and reconfiguring the driver would help; that’s the Windows way of doing things. If you thought that they were corrupted, simply reinstalling them would have been simpler. Have you tried the GUI interface into CUPS at

I removed and reinstalled the driver thinking it might have been a permissions or an selinux issue as a result of some update. That’s all.

I also removed the printer from ccpd and cupsd and re-initialised them using port 59687 instead of 59787 (as this had been suggested a couple of years ago when I was first installing the printer driver).

I have been on the CUPS GUI and that is where I was initiating the test print.

This is resolved into an IPv6 address by default:

> getent hosts localhost
::1             localhost localhost.localdomain localhost6 localhost6.localdomain6

So make sure it is listening on an IPv6 socket, otherwise use an IPv4 address explicitly.
In addition, it might be worth trying to temporarily disable SELinux or test other CUPS back-ends.

This is quite odd.

Even though the 2 popup notifications say printing, then printing complete, the cups logs says things like

Nov 03 20:19:24 gm-ws1 cupsd[10114]: [Client 39] con->http=0x55649cdb0360
Nov 03 20:19:24 gm-ws1 cupsd[10114]: [Client 39] cupsdWriteClient error=0, used=0, state=HTTP_STATE_GET_SEND, data_encoding=HTTP_ENCODING_CHUNKED, data_remaining=0, response=(nil)(), pipe_pid=13883, file=17
cupsd[10114]: [Client 39] Waiting for CGI data.
cupsd[10114]: [Client 39] CGI data ready to be sent.
cupsd[10114]: [Client 40] HTTP_STATE_WAITING Closing for error 32 (Broken pipe)
cupsd[10114]: [Client 40] Closing connection.

And the printer does not record any failed jobs. It’s as if the ccpd consumes the job but does not actually forward it to the printer.

I just noticed in the logs:

cupsd[14513]: PID 14798 (/usr/lib/cups/filter/pstocapt2) did not catch or ignore signal 13.

I found elsewhere this could be due to ghostscript. So lloking at dnf history of ghostscript updates I found 2 in October.

On 2020-10-17:

Upgrade ghostscript-9.53.3-1.fc32.x86_64 @updates

Upgrade ghostscript-9.53.1-2.fc32.x86_64 @updates
Upgraded ghostscript-9.52-7.fc32.x86_64 @@System

Am I barking up the wrong tree here? Or should I try rolling back ghostscript to a previous version?

If it were a permissions issue, you would have gotten an error message reporting it. If it were a SELinux issue, you would have received an alert. Since you didn’t, neither of those was an issue.

OK; a couple of things to add.

After all the adjustments and removing / installing, the Fedora 32 PC takes nearly 5 minutes to shutdown.

In the logs I find a CCPD timeout failure:

Nov 04 07:19:54 gm-ws1 systemd[1]: polkit.service: Consumed 1.270s CPU time.
Nov 04 07:24:52 gm-ws1 systemd[1]: ccpd.service: Stopping timed out. Terminating.

Add this to the possible ghostscript connection and the future of this printer is looking grim.

I also noticed that CUPS is saying that printer drivers are deprecated and will be removed in the next feature release. So I phoned Canon here in Aus, and they do not provide any support for linux. Nor do they have any IPP or Postscript laser printers. Not looking good.

I also noticed in the README file with the driver:

If you are using this driver in a 64-bit environment, and update a version 2.20 driver to version 2.30 or later, errors may occur when printing.
This problem can be solved by uninstalling (rpm -e [driver]) then re-installing (rpm -i [driver]) the new driver.

I did have an old version of the driver on the system some time ago, but cannot remember which version. Thus the remove and re-install the printer drivers.

I think I might spin up a Win7 VM and print from there until I choose a replacement printer. But that is another question all together.

Thanks to those who tried to help.
