Thank you for your help.

I'm a little perplexed, Kim, because CUPS appears not to detect your printer. Anyway, we'll leave that on one side and look at the error_log and at the line

  "DEVICE_URI=cnijnet:/00:1E:8F:74:5A:78"

I am not familiar with Canon printers, but this looks like a misconfiguration. From what I see elsewhere, it should be

  "DEVICE_URI=cnijnet:/00-1E-8F-74-5A-78"

I would expect this (ofter called JetDirect) to work too:

  "DEVICE_URI=socket://<IP_address_of_printer:9100>"

There should be a PPD for the print queue in /etc/cups/pppd. What does its *cupsFilter line show?

/etc/cups/ppd/MX860.ppd:
*cupsFilter: "application/vnd.cups-raster 100 rastertogutenprint.5.2"

There was an error above:
PpdFiles: Error: command ['fgrep', '-H', '*NickName', '/etc/cups/ppd/MX860.ppd'] failed with exit code 2: grep: /etc/cups/ppd/MX860.ppd: Permission denied

Is there an error with the permissions on this file?
-rw-r----- 1 root lp 131822 Dec 14 13:17 MX860.ppd

> -rw-r----- 1 root lp 131822 Dec 14 13:17 MX860.ppd

There is nothing wrong here. A PPD is not readable by a user process, only by one with root privileges. Whatever you ran did not have root privileges.

You are using the gutenprint PPD for MX860; no problem there.

Now do

 lpadmin -p mx860 -v socket://<IP_address_of_printer:9100> -E -P /etc/cups/ppd/MX860.ppd

and print with

 lp -d mx860 /etc/nsswitch.conf

I am guessing that the Canon printer accepts jobs on port 9100 - most printers do.

You could also set up lpadmin with -v cnijnet:/00-1E-8F-74-5A-78 and see how you go on.

The printer continues to be connectable via the printer web host.

I ran commands:
sudo lpadmin -p mx860 -v socket://192.168.1.87:9100 -E -P /etc/cups/ppd/MX860.ppd
and
lp -d mx860 /etc/nsswitch.conf

Looks good. But nothing printed, eh.

What do we have for

  nmap 192.168.1.87 ?

kim@kim-MS-7865:/etc/cups/ppd$ nmap 192.168.1.87

I think my only other option is to de-install and re-install the printer driver. That is a pain because Canon does not support Linux drivers. I have to search the web for the latest version from a hopefully reliable source. It takes a day. Doing this always results in inconsistent results for print and scan function on the printer. Sometimes only print works, other times only scan. Since this happened when I upgraded my machine to 18.04, re-installing may be the best answer.

Thanks.

Ok, there is no port 9100, so socket:// will not work. One lives and learns!

Looking at the error_log again all the filters complete successfully:

Search for "exited" and "normally".

All that cnijnet:/ does is transport what rastertogutenprint.5.2 produces to the printer. Perhaps the printer is unhappy with the input from gutenprint? I cannot test this.

I can only suggest you use the Canon drivers.

Let me know if you agree.

Thank you. It may be a week or two until I have time to reinstall drivers. I will repost if that helps. Let me know if I should do anything else today.

It seems that the only way to contact the printer is with the cnijjet backend. One last last thing if you would: execute

/usr/lib/cups/backend/cnijet

and give us the output.

Thanks for your co-operation.

Brian.

I get no output. It runs for about 5 seconds and returns to the prompt:
kim@kim-MS-7865:/usr/lib/cups/backend$ /usr/lib/cups/backend/cnijnet
kim@kim-MS-7865:/usr/lib/cups/backend$

Note that I changed the executable file name. I could not fine either cnijjet or cnijet.

Apologies for the typos.

The error_log has

  [Job 477] PID 5588 (/usr/lib/cups/backend/cnijnet) exited with no errors.

But you get no output. What is your CUPS version?

Brian.

Forget the last post, please. It's in the error_log.

Oops. I had previously turned off my printer. Now, with the printer on:
