[xx] is 0x01 on the CP780/CP800/CP900, 0x00 on all others.
[rr] is error code:
0x00 no error
0x01 paper out
0x04 ribbon problem
0x08 ribbon depleted
[ss] is either 0x00 or 0x70. Unsure as to its significance; perhaps it
means paper or ribbon is already set to go?
[pg] is as follows:
'P' paper 0x11
'L' paper 0x22
'C' paper 0x33
'W' paper 0x44
First four bits are paper, second four bits are the ribbon. They aren't
necessarily identical. So it's possible to have a code of, say,
0x41 if the 'Wide' paper tray is loaded with a 'P' ribbon. A '0' is used
to signify nothing being loaded.
[zz] is 0x01 when on battery power, 0x00 otherwise.
