Please enable debug logging for printing as follows: Select "System" ->
"Administration" -> "Printing" in the main menu of your desktop. The
printer setup tool system-config-printer will open. Select "Server
Settings" in the list on the left. Then check the checkbox "Save
debugging information for troubleshooting" and click "Apply".

Then scan and print an image and post /var/log/cups/error_log. This is
a file where CUPS writes information about what it is doing. Almost
all printing problems can be diagnosed from the error log, so it is
the first place to look to start solving problems.
