HP-19C Print

[teenix]

Hi all,

I'm not sure if this is a bug for the HP-19C or just my emulator, however under certain conditions, the printer fails to print.

An example is...

Turn calculator ON and into PGM mode.
Place the printer switch to NORM position
Press any keys, say EEX CLx ENTER
Switch back to RUN mode
Press [g][RTN]
Switch printer to TRC mode

Press SST any amount of times
The printer should print the executing program step but it doesn't

Press [g][RTN]

Press SST any amount of times
The printer now prints ok.

I traced this down to a value in RAM that doesn't get set when just using the SST button, however it does for [g][RTN] or any other function like [-][+] etc. Pressing numbers does not affect this setting either.

This RAM value determines whether the printer will print.

I cannot confirm this as I do not have a working 19C. If anyone else can confirm a real 19C does this, great, otherwise I have to play with the emulator.

cheers

Tony
