HP Deskjet 840C Printing Problem

This is probably something really obvious, but I cannot find it myself!

I currently have a Pentium II 433, loads of RAM and disk space, operating on W95. I have a Winwriter 150C connected to LPT1 and it works fine.

I am trying to set up a second printer, an HP Laserjet 840C to also print off LPT1. This printer works fine off of my laptop running on NT.

When I try installing the drivers I get an error message indicating that it cannot find the new printer on LPT1, even though the new printer is connected straight into the back of the PC with the same parallel cable that works on the laptop. Obviously, when I subsequently try to print, nothing happens.

Printing at the command prompt works fine.

What am I doing wrong?

Hmmm I think that winwriter doesn't just use a conventional driver that you can disable by selecting another printer, because it installs a lot of printer funtionality in it's windows specific drivers, offloading the work onto the PC and operating system, you may need to do a full uninstall of this printer, deleting it's driver and all parallel port drivers in safe mode before trying to install the LaserJet again.

I deleted the 150C and everything then worked fine on the HP. I re-installed the 150C and the HP stopped working again. I then disabled the Dos Printing on the 150C and re-booted. Hey presto, everything now works!

Thanks for the help.
