Does PHP has access to the parallel ? I'm trying to write data to the LPT1 port using PHP, but not having luck finding anything.

Writing to the parallel port is as simple as:

file_put_contents("/dev/lp0", "See that was easy.");

Your real problem however sounds to be:

Since PHP usually runs under Apache, the permissions for this device file are insufficient. On Debian systems you would add the www-data user to the lp group to make it work.
