Everyone keeps crying about thermal head degredation the second you bump duty cycles past standard 80us pulses on generic clone heads, but nobody seems to test passive aluminum heatsinks taped directly to the ceramic substrate. Sure, running 115200 baud over software serial on an unbuffered microcontroller is asking for dropped bytes and uneven line feed artifacts, but blame the sketchy timing loops instead of acting like the hardware is physically incapable of dark dithering at speed. Most people just burn their cheap receipt paper to a crisp with excessive heat profiles because they refuse to calibrate motor step delays to match the strobe pulses, then they run around claiming the firmware was bugged. Maybe if people spent five minutes scoping the voltage drop on the 24V rail instead of using undersized wall warts, we wouldnt have so many bad takes about faded prints during fast bitmap dumps.
