Hi,

Thank for your advise, will check it out.
BTW, do you had any sample for my reference

The sample from the OPOS from Espon does not work
for my win2k system.

I also using other printer brand like Star,
their OPOS does not work for me, I am at a loss.

BTW, do you use Unified POS standard at http://www.nrf-arts.org/.
What is the different between these two ?

Due to my application not working with OPOS, we are
still using the low level of communicating with the
printer.




>If you're using Epson TMT 88II more higher, check your firmware version. OPOS will not engage for earlier version. I think it has to be higher then version 3.14.

>Whatever devise you're using, check ythe firmware version. It's probably what's giving you trouble.
