Thank you for your input on this problem. It is evident that you are a
more sophisticated user than I. Following receipt of your note I went to
the Ubuntu installation menu and installed "printers" as well as the
printing that was already installed. I got there by searching for
'cups'. Once installed it did nothing to improve the duplex problem.
I may be missing something due to my lack of understanding. I do not
know how to check the system further. When I click on print in the file
menu there is clearly an option to do duplex printing but it does not
work. Again, any helpful input will be appreciated---I'll try anything
that fixes the problem but the problem should not be present at all!
