This is one of the specialized operating system which is designed mainly for servers. You could situate your printer almost a mile away from your PC if you had wire enough.Network Operating Systems (NOS): Windows & Novell Net Ware Network Operating System(NOS) I'm not sure which one this is, but at least you know what one looks like now.Īpparently short-haul parallel modems are still available. They came in both serial and parallel flavors. In the meantime, it would return a "not ready" status to the other PCs. The T-switch would connect when any system would begin printing and then keep the connection for a time after printing ceased. I used the former quite a bit when a laser printer would set you back a couple of thousand. There were also parallel link line extenders (converted the parallel signals to serial and used current-loop to cover long distances). If it's a direct write-to-port interface (as you might find in old WordStar), that's not going to be practical unless you use a gizmo that attaches to the parallel (or serial) port on the client system.Ī fairly routine setup in the bad old DOS days was an auto T-switch that hooked to the printer and several PCs. The big issue is how the DOS program that you're using interfaces to the printer. The protocol is a little more complex but every network printer probably understands it.įor background there is a discussion thread on FreeDOS here: I have not done a proper LPR print client yet - there is not a lot of demand for it. (Assuming you send it a reasonable data stream. If your printer is listening for connections on port 9100 then there is a good chance that it will work for you. The printer takes a raw data stream on that port and figures out what to do based on the data it receives. To print from DOS I used Netcat and had it connect on port 9100, which is the HP JetDirect port. My printer (a recent Brother network printer) does PCL, Postscript, and good old Epson MX emulation. It is just a matter of connecting to the right port on the printer and shoving the right bits at it. The short story is that there are about three different printing methods over TCP/IP. I have demonstrated it using mTCP Netcat which is using TCP/IP.
