Hi. To begin with, I have a freshly built RedHat Linux 8.0 box running samba 2.2.8a. The kernel version is 2.4.18-14. I downloaded and compiled samba from source. I am using LPRng-3.8.9-6 as my printing system. The attached printer is a Lexmark Z22 printer and it is attached to the parralel port. Problem: For the life of me, I can't get NT type clients, NT4, 2K and XP to print to samba.
