I found that link in the forums and I have been following along what 
they were doing.

The last bit: creating a link from one file to the other:
This:
-s /usr/lib/cups/backend-available/serial /usr/lib/cups/backend/serial

produces this:

wadesmart at wadesmart:/usr/lib/cups/backend-available$ sudo 
/usr/lib/cups/backend-available/serial /usr/lib/cups/backend/serial
Usage: /usr/lib/cups/backend-available/serial job-id user title copies 
options [file]

So I thought they meant do sudo :

wadesmart at wadesmart:/usr/lib/cups/backend-available$ sudo -s 
/usr/lib/cups/backend-available/serial /usr/lib/cups/backend/serial
/usr/lib/cups/backend-available/serial: 
/usr/lib/cups/backend-available/serial: cannot execute binary file
wadesmart at wadesmart:/usr/lib/cups/backend-available$
