Although not having seen this ever crash my T102, I did notice that having my Seiko DP-414 printer connected, but turned off, causes an increase in current draw on the T102 (likely on the M100 as well). Several 10s of milliamps if I recall correctly. Does cause the red LED to come on if batteries are low. If the printer is powered on, then no increase in current draw is noticed. This might vary depending on the brand of printer used.
