I'm trying to get a handle on using Microsoft Point of Service.

I have an Epson TI-20II connected to my computer via USB.  I have installed it and named it "Receipt"

I have this code in my application:

deviceInfo = posExplorer.GetDevice(DeviceType.CashDrawer, strLogicalName)
m_Drawer = posExplorer.CreateInstance(deviceInfo)

which comes from Epson's code examples.

I can't figure out what strLogicalName is supposed to be or where it is defined.
Earlier in my code, it's set up like this:

strLogicalName = "CashDrawer"
(since the application is trying to open the drawer through the receipt interface.)

I renamed the variable to Receipt to match the actual name of the printer.  But it's not working.
I've attached the sample program for what it's worth.

Any ideas on how I can connect to the printer/cash drawer?

Thanks for your help!!!

I'll preface this by saying I haven't worked with that API before.

I can't figure out what strLogicalName is supposed to be or where it is defined.
According to the documentation:

Before you use GetDevice, logical names must be configured for the device by using either PosDm.exe or WMI. You cannot pass the service object name for logicalName.

I couldn't figure out how to assign it a Logical name, I tried POSDM.EXE and WMI, but for some reason the device wasn't available after doing that. I've decided to just connect directly to the printer.

Thanks for your help.
