Hi Denis,

I'm just starting the test tonight, but I'd like to be sure these
lpadmin commands work : they always finish silently and there seem to be
no verbose mode for lpadmin. Is there a way I can check these options
are enabled or disabled, just to make sure the test is properly
performed ? I tried "lpoptions -l" but these "usb..." options do not
appear in the list.
Unfortunately, I think there is no such possibility, we just have to trust
that lpadmin did it's job.
Ah, apparently I was wrong, you can check whether the modes got actually reset 
looking for a line containing "Deleting <option>-default" in your error_log.

Cheers,

I don't reply to all since the test is not finished yet (to save paper, I print only when I need to print, so it takes more time to get the test finished).
Until now, here are the results :

a) Disable all printer-specific optimisations

the test failed, printing 3 copies of a 6 pages document : the first two were right, but the third failed

b) Try 'usb-no-reattach-default'

Printing 3 copies of a 6 pages document : OK
Printing 4 copies of a 2 pages document : OK
Printing 5 copies of a 1 page document : OK
Printing 5 copies of a 1 page document : OK
c) Try both 'usb-no-reattach-default' and 'usb-unidir-default'

Printing 5 copies of a 2 pages document : OK
Printing 3 copies of a 6 pages document : OK
Printing 2 copies of a 1 page document : OK
Printing 1 copies of a 1 page document : OK
Printing 2 copies of a 2 pages document : OK

d) Try 'usb-unidir-default'

Printing 1 copies of a 4 pages document : OK
Printing 1 copies of a 1 page document : OK
Printing 1 copies of a 1 page document : OK

I'm going on with d) test a little while, until I print more that ten documents... and will let you know the results
Regards,

Denis
