Hi All,
When I code
??? chr(27)+"mycontrolcodestring"
the printer seems to ignore the control string. I've seen some great threads on this subject for VPF (wish I was there), but I have to get this 2.6 Fox DOS app (running in NT's command window) to print duplex on a HP 5Si printer.

Printer has duplex hardware; I can duplex other output through the print manager.

Is there a way to pass "??? ..." control codes through NT to the printer?

TIA
