Sorry again, you haven't really supplied us with any information.
What is the exact configuration of your machine?
What motherboard, chipset, video card, memory, Lan, sound card, etc...
What type of printer?
How is it connected to the computer? USB? LPT?
If LPT: how is the LPT port set up in the BIOS?
What does dmesg say? (Post the output of dmesg)
