Take a look at this EE Post:

That should send you in the correct direction.

If you want to create a "CUSTOM" printer port just like a "LPR Port", VB won't work for you... you should write some C++ Code.

Take a look at this...
http://www.codeguru.com/Cpp/W-P/printing/article.php/c5893/

Here you will find a very usefull source code for a 100% complete Printer Port. Actually this code redirect the output of the printer to an Specific folder using as file name the document name. So, all you have to do is work on the specific network communication protocol to "send" each job to the printer instead of a file...

Have you decided wich protocol are you going to use for this?
I can recommend LPR (RFC 1179)...

Good Luck!

I have no idea what protocol to use.  Anything that can connect to a Network Printer.  Could you please give me more info on that connection.

Thanks

The easiest way of sending jobs to a printer is thru 9100 port.

All you have to do is open a TCP/IP Connection to the Printer IP Address on port 9100...
Once you are connected, you just have to start sending the printer data "as is"...
And then close the connection...

Unfortunatelly I don't have any sample code for that, but if you know VB, you can try with MSwinsock just to understand what I'm talking about.
