Dear Neil

Lots of good advice, thanks.

On the PC I tried the:
   sudo apt-get install cups=1.3.9-17ubuntu3.4 and got the following
stephanos at dell:~$ sudo apt-get install cups=1.3.9-17ubuntu3.4
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Version ‘1.3.9-17ubuntu3.4’ for ‘cups’ was not found
stephanos at dell:~$

Next I tried Synaptic and indeed found several entries such as
cups          1.3.9-17ubuntu3.6
cups-bsd      1.3.9-17ubuntu3.6
cups-dbg      1.3.9-17ubuntu3.6
cups-common   1.3.9-17ubuntu3.6
libcups2      1.3.9-17ubuntu3.6

Each noted that version 3.7 was available and when I followed the 
Package > Force Version for each of the above, I was offered 3.7 and 
what I think was a lesser version: 1.3.9-17ubuntu1 (Jaunty).  I tried 
this for the first package cups 1.3.9-17ubuntu3.6 but this did not bring 
the printer option I need.

I used Synaptic to upgrade to 3.7 but that did not help either.

Thanks for the assistance.

Hope to hear from Neil or anyone with further suggestions

Stephen
