In the end I got through my problem using the cups web interface. I 
could see that CUPS had chosen on my laptop another driver than that in 
the old desktop, despites the fact that this driver did exist in the 
list displayed. So, I tried to select the Gutenprint driver on the 
laptop and then save the new settings. The system replied: 'Your 
settings have been changed successfully'... but this reply was 
inappropriate and must be a mistake in the program... for, upon viewing 
the "new" settings, I could see that the old driver was still there, 
that is 'HP Deskjet 1120, hpcups3.14.3'. Several trials all lead to the 
same result... until I found what was wrong. The system would not accept 
my new choice of driver because my earlier choices in configuring 'CUPS' 
did not comply with said driver ; I was stuck to the only driver that 
was compatible. Now, what were these earlier choices that forbid using 
the Gutenprint driver ?  It took awhile and quite a few tests before I 
could find what was wrong. Each time I tried to modify that printer, it 
never would accept any other option than that of a Network printer. 
Then, being compelled to write a network  address, I had no other choice 
than to write: "http://localhost:631"... which did work... but only with 
said driver 'HP Deskjet 1120, hpcups3.14.3' that provided very few 
printing options. The trick was not to try modifying, but to 'UNINSTALL' 
everything. Only then, starting from a clean config, was I able to 
choose a 'local' printer, which choice allowed me to the driver 'HP 
DeskJet 1120C - CUPS+Gutenprint v5.2.10-pre2'... in fact this choice was 
the default one !  And now, everything works all right and I get the 
same printing options as in my old system.

I have wondered about writing all those details above, but I thought 
this might help someone fighting with the same problem.

Thanks for your help,

Bernard

As far of finding what driver 'cups' has chosen for my printer

cups + gutenprint v5.0.2(en) for the old system using guenine parallel port
