Re: [Freedos-user] Setting up a shared printer
A very good Wiki page on printing with netcat! Netcat can be used in many ways. I find connecting to a command shell on a Windows PC and transfering files an interesting application. I did not have a chance to test that yet though. If a windows printer is configured to be used from that command shell you could also print the files that were transfered to the Windows PC - even if its a cheap windows-only printer.

Re: [Freedos-user] Setting up a shared printer
While only indirectly related to mtcp and netcat, I accidentally ran across this site recently: http://lspppacm.narod.ru It creates a DOS packet driver using a ppp connection through a USB modem. I haven't tried it (don't have a USB modem), but I think it's at least interesting, if not perhaps useful for some people. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Freedos-user] Setting up a shared printer
If your network attached printer is listening on TCP/IP port 9100 (HP JetDirect protocol) and your DOS program can generate something the printer can understand, then do the following: - Print your printer output to a file - Send the file to the printer using this command: nc -target printer address 9100 -bin filename Substitute printer address with the IP address of your printer and filename with the filename your program generated when you said print to file. For example, on my printer: nc -target 192.168.2.20 9100 -bin testfile.txt Will print testfile.txt over the network to the printer. (testfile.txt gets redirected on stdin to netcat.) Here is the fine print: Most new network attached printers will listen on port 9100. Yours might not. If it does nothing then it might be listening on the Unix LPD port (515) or the IPP port (631). Just try it, nothing bad will happen. Your DOS program has to generate output that your printer understands. That is usually some form of PCL output. Some printers can take raw ASCII text, some more expensive printers can do PostScript, and some cheap and nasty printers require Windows and can't do anything by themselves. If you have a printer that does not do ASCII, PostScript, or PCL and requires a Windows machine to do anything, it won't work for you.
