Hi,

Thank for your advise, I had log all error, there is
nothing wrong, just that insteads of normal trigger
my POS drawer to open, it just print out the command
that I sent to it.

The PrinterDev is one those the printer vcx class that
I place on the ole class

>Try setting unattended mode with SYS(2335, 0) so that any UI generated by the DLL causes an error, write the error to a text file in your Error() proc. If there is an error, try to build your project as an exe instead.
