Printing bar codes with HP 41?

[Hans-Peter]

There was a way with the 82143 and some HW modifications (additional switches) and some syntethic tricks to print barcode on the first hp14 printer. My printer has the outer switch to change the linefeed to half way, but the inner switch is not in use (I have to fix it). The handling was terrible with the program to print barcode.
A better way would be a IR module for a PC and a software witch can print barcode to a letter format.
I nice project for cracks.
