Where can I do this? I can't find anyplace where there is an option
to select "the printer that is having problems" and/or where to set
Default options to "retry-job"

At this browser address: http://127.0.0.1:631/printers/
there is a "printers" tab, but under that I cannot find
any place to set default options.

Also cannot find anything like that in "Control Center"

At this location, this is what I find:

-rw------- 1 root sys 130 Mar 7 21:55 printers.conf.O
-rw------- 1 root sys 130 Mar 7 21:56 printers.conf

And here is the content of "printers.conf":

# Printer configuration file for CUPS v1.4.6
# Written by cupsd on 2012-03-07 22:05
# DO NOT EDIT THIS FILE WHEN CUPSD IS RUNNING

How should I edit that file? What content should be added there?

Note that if one or both lines start with “iF” instead of “ii” then this appears to signify the installation failed to complete correctly. Remove the installation completely by editing (AFTER BACKING UP ALL FILES to be able to roll back after):

1. In System, Administration, Printers, delete the printer in question. You might also need to browse to http://localhost:631 and delete it in the CUPS printer list if it shows up there.

2. Go into a terminal, then gksudo nautilus
which will open Nautilus with root permissions.

3. Use nautilus to go to folder /var/lib/dpkg/info

Find all of the files that are named with your printer concatenated with "cupswrapper" "${printername}cupswrapper..." and delete them.

sudo grep $printername *
del $filename

4. Go back a level to folder /var/lib/dpkg and open the file called "status" in gEdit. Do a File Save As and called it status.backup. Close, and re-open the file "status" (not the backup copy). Search for "$printername". You should find a paragraph starting with the words "Package: $printernamecupswrapper" Delete that section and save the file.

5. Now repeat the process outlined in step 4, but with the file called "available".

You should now be able to go to a terminal and run sudo dpkg --configure -a without any errors.
