How to use /dev/lp0

I need this urgently, so what i want is, how to use the /dev files for the parallel port, instead of the outb() or inb() functions.

You can either open the device file and write to it with standard file operations, or you can redirect output from commands to the /dev/lp0 device file:
cat some_file.prn > /dev/lp0

But is this really what you want? I would use a queuing system like lpr or cups. Is there a reason why you want to access the hardware directly?

I want to acces the hardware directly because is a little project i have in a subject.
The intention is to write to the paralel port and print messages on a Character LCD Display.
But is finished now, and i thankyou for your response.
Its working fine and i learn how to use the file /dev/port for the interfacing.
Again, thankyou for the response.
