Opening a POS Cash Drawer in C# with OPOS

Posted on 2008-11-13

I have an EPSON TM-T88IV that is connected thru a USB port and my cash drawer is connected to it.  I have EPSON OPOS for .NET and have been trying to get it to kick open in my C# code and have been having no success.  The printer will print and cut the paper without any difficulty, but there is no response what so ever from the drawer.  If anybody can help me out with the code and/or settings it would be much appreciated.

    I take this snippet of info from the following link to a question here. <~~~~ this one explains how it works, and how to get it working posibly. <~~~~~ this one shows some VB scripts on how to do different things, like cutting paper and opening the cash drawer. Its VB based though, but it might put you in the right direction.

    That very well could be the solution to my problems and I just can't understand it.  But it says that the code should be 27,112,48,55,121... What do I do with that?  I mean the code to cut was 27, 109 but I just used
