You may be able to change the port setting in your BIOS, most newer BIOS
allow this.

Hello list!
I have spent some time installing Epson P2100 (aka P2200 in the U.S.) - the
USB connection did not work (printer was recognised, but any access to it
caused only a quick double-tick of the printing head and nothing more). The
good thing was that it supports also the parallel connection.
Once connected via /dev/lpt0, the printer worked, but printed _very_ slowly
(and /var/log/messages announced irq storm on irq7).
A search on google revealed that it is possible to switch the port mode
to "extended polling" by command "lptcontrol -e -d /dev/lpt0". Then, the
printer worked normally.
"ltpcontrol" supports only connected (and powered on) printers, which is
usually not the case during boot, and it must be run with root privileges.
My question: how do I set the default port mode to "extended polling" instead
of "iterrupt driven" during the boot process?
Thanks for ideas,
Milan
