Parallell printer port problems.
 
When booting my system, the parallell port (lpa0) is only
recognized if the printer is unconnected (from the computer).
 
If I boot without the printer connected, and then connect the
parallell cable, everything works fine.
 
First I thought the problem was in my printer port, so I bought
a new one (lpt0), but the result was the same.
 
The printer I'm using is an OKI OL 400 Laser printer, and the
computer is 486DX "noname", and I am running netBSD 0.9.
 
I have previosly used DOS WINDOWS COHERENT without problems.
 
By using the dos program MSD I found these differences between
a connect and disconnect printer
 
                 On_Line Paper_Out I/O_Err Time_Out Busy  Ack
Disconnected       Yes      Yes      No       No    Yes   No
------------
Connected and
Turned Off         No       No       Yes      No    No    No
Off-Line           No       No       No       No    Yes   No
On Line            Yes      No       No       No    No    No
 
Do you think the problem has to do with my printer port, or is it 
the combination of lp device driver and my printer that cause
this problem.
 
Is there a way to force him to load the driver?
 
Except from this problem, the system is runnig great, and
as a poor student I am very thankful to at last be able to
run a real operating system
 
I would be very greatful for any form of responce.
 
Thanks
