I have never dealt with these wonderful but noisy printers except to install a driver once. I need to TROUBLESHOOT a second printer on a an HP Pavillion 7975 with dos and no windows. Not remembering a lot with dos, where should I start and where should I look for info/direction on printer functionality.


Thanks!! DOS does not require printer drivers, so your off the  hook there

it's usually sufficient to Copy a file to the PRN device or LPT1, or, for asynchronous printing, use the "print" command.As I go through the config.sys I see where NMDOSIN (?) is doing something with LPT2=SPP with -A -C switches
then
NETMOS dos installer


When netmos PCI device is found on bus02 slot0A it reads:
IRQ=255 : IRQ not programmed correctly
BIOS failed to program this device
Detected 1 pci device
com1 exists at 3F8
com2 exists at 2F8
LPT1 exists at 378

I assume that's why one printer is not working but does the bios need to program the device?
I am not sure how the PRN works or how to access it-yet.
What is NMDOSIN and what is happening with LPT 1 and 2?
Any direction would be great, I have been googling...finding not much. I have not found the right thread here but hope to create it or still look for it.
Any thoughts?

Thanks,
