No printing EPSON TM-20III - Teensy 3.6

[MatthijsHoekstra]

Printer gets detected by Printer.ino example in the USB Host Teensy 3.6 example.

USB Host Testing - Printer

*** Device 4b8:e28 - connected ***
manufacturer: EPSON
product: TM-T20III
Serial: 583741561767360000

Unfortunately, it does not respond on sending anything over Serial in the example. Neither does any of the example work here in this repo.

Is there any chance you could give me a hand in discovering what the issue might be?
