[Samba] printer access slow

[erik thijs]

Hi,

I installed a samba printer, that maps to a script to generate pdf files. It 
works, but there's a notable delay when selecting or printing to the 
printer: when I click 'print' in an application and I select the samba 
printer, there's a delay of about 5 to 10 seconds before the printer is 
accepted, and I can effectively print.

Any clues on what could be the cause (and the resolution :) ) See configs 
below...
