cups printing

[Nic Deane <nic@ntbd.uklinux.net>]

I run Fedora Core 4 as a dual boot with Windows XP on an e270 e-machine
- 1.7 Ghz with a LazerJet 4 Plus as my default printer. For OpenOffice
documents and all other printing this works fine.

I downloaded dosemu to run an old DOS PIM called Portex which I love and
have lots of Filofax papers set up on. I really am trying to move
completely over to Linux! In Windows I have to set my default printer as
HP LJ 2-6 LPI and this prints through my HP LJ 4 Plus. In dosemu I can
load the document I want but when I set it to print it comes up with the
error message lpr: error - unable to print file: client-error-not-found

I tried gedit on /etc/dosemu/dosemu.conf and took out the # at the
beginning of the lines and saved

$_printer = "lp"
$_printer_command = "lpr -l"

and then re-ran my print command but this didn't make any difference.
Should I have re-booted? I didn't think I had to do this in Linux.

Any ideas?

Many thanks,

Nic
