I'm not sure if it will work with a blank password but I may be wrong.

Yast has succesfully founbd my printer.
The problem now is something else.
When yast finds the printer he wants to select the printer of a list....i choose it but i cant print......
If i dont select a printer and i choose postcript printer then i can print but i take a small text that i can read...
What i must do know?

Try experimenting with different drivers or try downloading some new/updated ones from the manufacturers site (if they have linux ones)

xmmm.
 

My printer is 1995 model......I think tha suse must have the correct drivers
