quickbasic 4.5 : get a return code from a LPT port

[KateCM]

I would like to read a return code from an parallel port.
I open a LPT port as OUTPUT
I have an EPSON printer with a drawer behind it
I send a command to the printer to know the drawer state (close or open)
When I want to read the state with an INPUT$, quickbasic tell that it can't read from an output file; but I can only open this file with OUTPUT.
How can I do to get this retun code

You shouldn't try to communicate directly to the printer. Get a list of interrupts so that you can ommunicate with the printers driver.

Look in the help files for:

Errdev and Errdev$
IOCtrl and IOCtrl$

these may help.

KateCM,

What sort of Epson printer do you have and where did you get it from?. I think you may be talking about Epson PoS printers in which case I can help you out, but I need to know the printer model and where it came from.
