Digital BW, The Print

I was  the first one to make this request and appreciate all the help.  
I can now run the program and I know how to edit the file however I have 
yet to get it to print.  My 2200 is connected via a usb port to my 
computer.  I set it up as a shared printer per the instructions, however 
I don't think I  have the required type of "network".
The errors I get in the file include comments about LPT3 ( Is this not 
the parallel port?) as well as   "System error 66 has occurred",  "The 
network resource type is not correct" and "The system cannot find the 
path specified".
Clearly I have a "networking" problem.   I will be gone for the next few 
days and look forward to
any advice I may receive in the meantime,
Mike
