The character set is hard coded in the printer's ROM whereas graphics
are sent using an escape sequence followed by numbers which tell the
printer how many dot columns are to be printed and which dots to turn on.
These numbers are the same for both the HP82240 A and B which means
graphics (including printing an image of the display) will print the same
on both versions of the printers. The keys to 'hot-key' the screen on the
HP48 are ON-MTH.
