please help me in writing dot matrix printer driver

[harinibontadkar]

hi, i am new to kernel programming. i am writing driver for character printers. my driver sends the data to the device file but it is not getting printed by the printer. i feel i have missed out the printer initialization commands in the code. What are the signals that are to be sent to the parallelport port to initialise the printer and send the data to print it? Please help.

I really don't know the first thing about writing drivers, but I need to learn it. Here's probably the most important book you'll need on a project like this, if you don't already have it.
