TM T88III Feature List incorrect

[sam-vdp]

I have recently attempted to use the QR Code [GS(k] and graphics image [GS(L] on an Epson TM T88III printer. In both cases I sent the data from the unit test testGraphicsBlack and testQRCodeDefaults to the printer. Neither worked, graphics image simply does nothing and the QR code outputs some ASCII fragments of the command.

The Epson programming guide explicitly lists the TM-T88III as not supporting the GS(k and GS(L commands. I therefore believe the feature list for this printer is incorrect.
