Canon Multi Pass 600: small size

[Olivier Bokanowski]

I have a Canon Pixma MP600 
Installed with cups printing system + linux mandrake 
I used the canonip4200.ppd file
(I followed the instructions on 

 http://www.linuxprinting.org/show_printer.cgi?recnum=Canon-PIXMA_MP600

I can print but it prints out with small size (size 1/2).
option -o scaling=200 
do not modify anything

I dont know what to look for.

Will be gratefull for any help
