I hope this is the right forum to post this in, it seemed the best fit for the question.
Ok, we have an IBM Thinkpad running specialist auto diagnostic software built on a custom build of SCO linux - I say custom as I don't seem to be able to alter any of the configuration.
We really need to be able to print from it, but it only prints in PS format to a limited number of printers and despite having a network printer which allegedly offers PC5/PC6 and PS support it just prints pages and pages of garbage.
As this didn't work, I have set up a virtual PS printer on a nearby XP box using Ghostscript and Redmon to try printing across the network from the auto diagnostic pc. I have verified it works, so I'm pretty sure that's not the problem.
Since this (really freaking annoying) software has to be on a specific IP address, I wanted to take it off our general network, so I have connected the two computers with a crossover Ethernet cable and given them correct IP addresses to be able to connect.
The problem is, the software on the diagnostic computer has no ability to see Windows or a an shared printer, only to print to a specific IP address. Because of this I am trying to find if there is a way that I can get the Windows XP PC to accept any data sent to its IP address to print to the Virtual PS printer?
I used Wireshark to look at the traffic on the cable and there is a print request from the auto diagnostic PC to the XP box on Port 9100. However, the XP box only sends back a Reset command in the other direction. The auto diagnostic PC continues to send requests but the same thing happens and nothing prints.
Sorry for the long post, but I wanted to explain the situation as best I could. I have tried so many ways to do this, but just can't seem to find the right setting or missing link in the chain.
