special characters on hp71b + hp-il + 82162a ? - John Ioannidis - 01-26-2010

I'm trying to do the HP41's equivalent of BLDSPC and ACSPC.

I tried creating a character with CHRSET, it displays fine on the display (DISP CHR$(128)), but prints nothing when I do PRINT CHR$(128).

What am I missing?

Hi

The 71B CHARSET characters are not equivalent to any printer.
The format is 8 * 6 bits.

The 82162A uses 7 bits for characters.

Closest approach: use only 7 bits of the CHARSET character set.
Assuming a 82162A, put the device in Graphics Mode, get the correct substring of CHARSET$ and send it to the printer.
