To connect a serial printer to IBM PC, the following are needed:

1. Check DOS menaul about "MODE" command to set your com2, it has to match your
   printer.  i.e. 9600,n,8,1,p
2. Check your cable, pin 2 and 3 might need to be twisted.  Find the detail in
   RS232 spec. in your printer's manual.

After your MODE is set to the right mode, try to print the screen.  If nothing
happen and your PC freezed, check the cable.  If anything printed on the printerbut they are not "readable", you have wrong setup.

Also, unless you have a fast enough printer or big enough buffer on the printer,you'd better reduce 9600 to lower speed.  :
