We are working on a component related to retailers and their point of sale applications, and it's primary functionality is to capture the printed receipts text.
Most Pos application the print through OPOS printers drivers. so far, we have developed a service object (SO) using the Pos for .Net api's.
We need a similar SO, but an OPOS one, to handle all other Pos applications that does not support the Pos for .Net, but rather deal with the legacy OPOS devices.
So, we need a COM PosPrint service object, that will define an internal "original printer" (can read it's name from registry for instance), then it should forward all invocations to the original printer. while doing that, it should capture the printed texts, and save it to a text file.
