Well first of all, You will need the API installed on Your computer. Please Do check with Epson's WebSite or with Your dealer for the driver that contains the API. It's been a long time since I worked with it but I think it was in the normal driver's package.

You will have EpsStmApi.Dll on Your computer then. Please check for that.

Once this is done, It should be something like:

loDrawer = newobject("cstDrawer", "MyClass.vcx")

*-- Set the Printer-Driver's Name
loDrawer.c_Driver = "EPSON TM-T88II(R) Receipt"

*-- Set the drawer, that should be opened. 
*-- Some Printers allow to drive two drawer.
loDrawer.n_Drawer = 1

*-- ... and how long the pulse should be
loDrawer.n_Pulse = 1

*-- Then try to open it and if it fails, check 
*-- the Errortext
if ! loDrawer.OpenDrawer()
    MessageBox("Oooops..."+ loDrawer.c_ErrorText)
endif

That should be it. Most of the Properties You do not even have to be set, as the standard values will do or can be pre-set in the class.
