I have thermal printer from adafruit and when printing images I have problems getting a proper black.
I tried playing with the dot print time and the dot feed time using the
setTimes function, but this seem to have no effect.
unsigned long dotPrintTime = 3000*30L; unsigned long dotFeedTime = 2100*30L; printer.setTimes(dotPrintTime, dotFeedTime);
setHeatConfig seems to have no effect. I tried different values.
uint8_t dots = 11; uint8_t _time = 120; uint8_t interval = 40; printer.setHeatConfig(dots, _time, interval);
Here an image of the result:
Is it possible to print fully black the whole width of the paper?
