Hi!

I have looked online for the specifications of your computer.  It is
clear to me that it has no parallel port device.  FreeDOS cannot use
some of the recent interface types which might be used to provide a
legacy hardware device e.g. to Windows operating systems.

Well you might be able use a PCI or PCIe extension card which
provides a parallel port if it were a desktop, but not for your
laptop. The usual answer would be USB, but your mileage may vary
regarding the ability to use those with current DOS USB drivers.

In any case don't forget that a laser printer is a page printer, not a
line printer and that many old DOS applications will not know that...

It may expect either plain text or PS or PDF as input, which are
all feasible to create in DOS. At some point, dumb printers which
needed smart drivers were popular: Those GDI printers will only
work with operating systems supporting big complex drivers, no DOS.

But as Frank wrote, network might be useful. In some cases, using
a laser printer from DOS could be as "easy" as:

netcat 12.34.56.78 9100 < yourfile.pdf

where 12.34.56.78 is the IP address of your printer. Interestingly,
you may have to ^C the netcat to tell the printer that your print
job is done and let the printing start. In any case, you do not
need any special printer driver for this: You only need a driver
for your network, and the netcat tool.

Using network in DOS is a lot easier via LAN than via WiFi. You
may want to use a router or bridge so you can connect the laptop
via LAN if you would normally only use WiFi, to protect DOS from
having to understand anything about WiFi.

Regards, Eric
