sir,
I need to develop a HP LASER JET PRINTER Driver to interface the PIC microcontroller directly,
could any one help me how to write printer driver for PIC Microcontroller for interfacing printer.How it could recognise the controller,what are commands we have to use,in which language should I write?
thank you in advance.

Have a look at "inpout.dll" available from http://www.logix4u.net and others. Suggest you learn C or C++ - plenty of relevant commands there!

Update:
You don't mention what OS you're using. In Win98 and previous, the printer port can be accessed directly with 'C' "inport()" and "outport()" functions. After Win98, the OS gets a bit picky about direct hardware access so you'll probably have to use inpout32.dll as an interface. Are you trying to program the PIC chip, or just want to interface to a pre-programmed PIC?
