The printing takes place in exactly the same way as previewing the document with ShowDVI. Please take note again, that you here also need more for printing than what there is to find on both disks TeXDisk1 and TeXDisk2.
As printers of different manufacturers sometimes distinctly differ, you must tell the printer driver, what printer is connected. It can drive 9 pins, 24 pins (NEC-P6 compatible) and HP printers. You can tell it what printer is connected with the -d option.
Following calls are for example possible:
For a 9 pins printer: DVIprint -d 5 testfile
For a 24 pins printer: DVIprint -d 1 testfile
For a HP printer: DVIprint -d 3 testfile
After that, you should hold a really nice printout in your hands.
