Point of Sale - Use of Open Standards 2

[koala15]

I am writing a POS app that needs to be device (printer, cash drawer etc) independant.

There is a standard object model called "OPOS" that seems to have all the objects I need and even has examples in VB6.

However, the standards people don't actually provide the SDK, just the documentation. The standards web site says to get the SDK from HW manufactures. I have done that (eg Star Micronics) and it seems OK (I have not run it yet) but I need the SDK to work with nearly anyones HW.

Comments and suggestions please.

Thanks in advance.

Greg.

Did you checked out

http://www.monroecs.com?

Here you'll find them Common Control Objects, which will enable you to code vendor independent.
So what you get is:
application <-> CCO's <-> Service Object
and the only thing to worry about is the interface between your application and the CCO's

Using them CCO's, you're done. I have customers using Epson, Star, Citizen, IBM, Ithaca peripherals without any problems (well, apart from my own bugs..)
