Printing to a smb printer

[Bruno Despin]

Thanks in advance to any support.

    I'm currently printing from Fedora to a Canon MPC 190 attached to a 
Win XP PC through SMB using the BCJ 600 driver. Everything looks fine 
except thay my printout is scaled down to approximately 50% of  my A4 
paper. This happens when printing test pages and printing from ooffice 
as well. Does anybody know how to get rid of it? To my understanding, 
pstops filter could do that but I don't know if there is anyway to 
define the scale parameter but from a command line.
