It is possible to create custom chars too with bitmap calculator.
Moreover WinLcd is a great parallel port monitor so you can
use it to check the printer port status.
In
file menu you'll find the connection diagram to connect lcd
display to PC parallel Port.
The program is very simple to use. Maybe you have to change
the delay time if you have a very fast PC.
If you can't see anything on your lcd,check the contrast voltage.
This program has an automatic line feed function for 4 lines
display.

order:
Line

Line 2 ---> Lcd Line 3
Line

Line 4 ---> Lcd Line 4
