[Samba] Printing jobs very big

[Xavi León]

Hi!
anyone knows why depending on the driver i use in the samba printer share
the jobs can differ in 4-5 MB?? I mean, if i use the Windows Driver 
(UNIDRV, etc...)
the job is ok (not very big, 40K) but the accounting in the server is 
always one page.
On the other side, if i use the Windows postscript driver (PSCRIPT5.DLL, 
etc...)
to print the same doc i get a job of  4-5 MB (the accounting this time 
is ok, 3 pages).
I cannot achieve why this is happening... any ideas???
