UpsideDownOn

[jlcmoore]

I seem to be unable to get upside down printing working on the thermal printer I have connected to a raspberry pi.

The following:

printer = Adafruit_Thermal.Adafruit_Thermal('/dev/serial0', 19200, timeout=5)
printer.upsideDownOn()
printer.println("hello")

prints in the same manner had I not called upsideDownOn().

Does this feature actually exist? Is this an issue with the inherited pyserial code?

Thanks for the help!
