after an update beta2->beta3, the local printer do not works no more (in fact I
don't know if it worked on beta2, but in beta1 it did)

it's a deskjet 930C on /dev/lp0.

I can't delete the line of this printer in yast (shown "not configured"). If I
try  to configure it, I get afterward the message "vous utilisez un spouleur
différent" (you are using a different spooler);
If I try to add a printer, the new printer takes the place of the non configured
one (only if i give the same printer model), but what ever try I did, same error.
When exiting ysat, I have the cups error message: cups(file)
DoRequesterror:client-error-not-possible
I attach the Yast logs
