[Samba] Letter printing in samba

[Ruben Rubio Rey]

Hi,

I have a samba server (Ubuntu 5.04) with Laserjet 3300 and drivers hpoj. 
Windows computers prints using the samba server. (By the way, windows 
computers can print but windows says when u click on printer icon that 
"Access Denied")

The problem is the WIndows computers only can print in A4. They cant 
print any other sizes, like letters.

Any ideas?

Thanks in advance.
