Error Codes
The error codes that may be transmitted by the Printer are described here.
Lowercase "v"
There is an input buffer overflow situation.
Uppercase "R"
This code is sent every time the Printer is turned ON. It signals that there
was a hardware reset.
Uppercase "T"
This code signals that there was a software reset. A software reset results
from sending the # command sequence to the Printer or by doing a
front panel reset.
