Working theory of interpreting the status flags:
MM :: 00 is idle, else mechanical printer state.
NN :: Remaining prints in job, or 0x00 0x00 when idle.
QQ :: ?? 0x3e + 0x40 or 0x80 (see below)
RR :: ?? 0x00 is idle, 0x40 or 0x80 is "printing"?
SS :: ?? 0x00 means "ready for another print" but 0x01 is "busy"
TT :: ?? seen values between 0x7c through 0x96)
UU :: ?? seen values between 0x43 and 0x4c -- temperature?
