"You're not incrementing $line" was my first impression, but in fact you have $line as the text you want, then you use it as an array index which probably evaluates to zero. To top it off, you assign to $line using that.

Also, it's a good idea to open an close handles at the same level, and to check for errors on system interfaces like open. Your &get_text sub takes no arguments, and really doesnt seem to add much to the organisation. Here is a decrufted version:

use Fcntl qw(LOCK_EX);
open DOM_WORK, '> /usr/spool/lpd/dom/dom.work' or die $!;
LOCK: {
    flock DOM_WORK, LOCK_EX or die $!;
}
for (<>) {
    tr/\x0c-\x0d//d;
    print DOM_WORK or die $!;
}
close DOM_WORK or die $!;
&get_domkey; # whatever that is

I added locking in case of contention for the file. You may want to redo instead of dying, so I threw in the bareblock around that. If dom.work is some sort of queue, you probably want to open it to append ('>>')
