I do not have a /proc/parport. Is that a problem? <br>
<br>
>From man tunelp, I read:<br>
<br>
"-i <IRQ><br>
specifies the IRQ to use for the parallel port in question.
If<br>
this is set to something non-zero, -t and -c have no effect. If<br>
your port does not use interrupts, this option will make print$B!>(B<br>
ing stop. The command tunelp -i 0 restores non-interrupt driven<br>
(polling) action, and your printer should work again."<br>
<br>
Sounds great. But...<br>
<br>
nahash@ubuntu:/$ tunelp /dev/lp0 -i 0<br>
tunelp: ioctl: Invalid argument<br>
/dev/lp0 using IRQ 7<br>
nahash@ubuntu:/$<br>
<br>
Others have the problem<br>

<br>
But noone seems to have the solution.<br>
<br>
Any other suggestions?<br>
Thanks.<br>
