ESC ? — Reassign Graphics Mode
This command sequence changes one graphics mode to another. The vari-
able s is a character (K,L,Y, or Z) which is reassigned to a mode n (0–7).

ESC + — Print Character Graphics
This command sequence enables the printing of character graphics. The
variable n is the length of the character graphics string. The variable d rep-
resents the character graphics data stream for a length of n characters. The
value of the characters in the graphics data string may be from 0–255.
With this command, certain character values 0–31 are printable graphics
symbols rather than non-printable control codes. See ESC I for limitations.

ESC t — Print Character Graphics
The desired behavior is that this command is allowed for compatibility
with the 6820 80-Column Printer but causes no action on the PK80
Printer. The default behavior for the PK80 Printer is ESC t 1, character
graphics enabled. If any graphics characters are taller than nine dots, the
printer advances the paper and prints the remaining dots. Any space ad-
vanced by the printer reduces the distance advanced by the printer when
the next line-feed occurs.
However, if it is determined that this desired behavior too greatly impacts
development time or printer speed, an allowable alternative is as follows:
This command sequence controls the printing of character graphics.
When the variable n = 0, graphics characters taller than nine dots are
truncated, only the top nine dots of the character are printed. When n =
1, graphics characters are printed in their entirety, the printer prints one
line, then if necessary, advances the paper and prints another. Any space
advanced by the printer reduces the distance advanced by the printer
when the next line-feed occurs. The default mode is ESC t 0.
