Macro Definition Documentation

BYTE_TIME

#define BYTE_TIME   (((11L * 1000000L) + (BAUDRATE / 2)) / BAUDRATE)

Number of microseconds to issue one byte to the printer. 11 bits (not 8) to accommodate idle, start and stop bits. Idle time might be unnecessary, but erring on side of caution here.

INVERSE_MASK

#define INVERSE_MASK   (1 << 1)

firmware (see inverseOn())

Turn on/off white/black reverse printing mode. Not in 2.6.8
