I know you can do it, but I don't remember how. I think you need to setup LPR3 (or LPR4) in App Log Port Assignment, but I can't seem to make it work.

Thanks!

You need to first disable host printing and enable raw print mode in ProComm. Then go to maintenance, issues your formprint command, i.e.

formprint multiline set assignment /port lpr3

Then you need to issue an enable print command.

en pr

At that point you will see your formprint scroll the screen. Either have a capture file set up or print capture (or have a large enough scroll buffer in Procomm). After you see formprint complete message, issue a Ctrl-C to get back to maintenance mode.

My experience has been that after you issue the en pr command, the form print will go to the default printer of the PC hosting your ProComm.
