how to use printer port in motherboard?

Question

for my project name "Smart controller for intelligent home"

Answer 1

Check out the manual/specs for your motherboard to see what port IC's are being used (or emulated).

Look up specs for that particular IC on the internet

Go back to motherboard manual/specs to determine which port numbers(s) and interrupt(s) are used for the intended port. Or query the harware stuff under my computer.
(These are usually fairly standard, but I don't remember what they are anymore)

Perform I/O reads and writes to the appropriate port numbers according to descriptions in the post IC's details found online. I use assembly, but I am sure most decent languages have facility for port I/O. However, your OS may try to prevent you from accessing these directly, and doing so CAN muck up your system.

This is not for the faint of heart. I recommend getting a book (or online tutorial) on port I/O programming on your particular OS, using your particular language.

Answer 2

Do you mean programically - like LPT1 in DOS or do you want suggested uses for the printer port that is already there, lik"printing out recipes" Since most printers are now USB, you might end up hanging an adaptor on it. The printer port does not have sufficient drive for doing anything over any length of wires, so it can only be used locally, like for indicator lights. You may find no use for it - I certainly wouldn't much if I were carrying out what I thought were reasonable (and expensive) plans for an intelligent home.
