C-32
The bits of parameter "p" identify the print modes selected:
b8: = 0 fixed
b7: = 1 fixed
b6: = 0 fixed
b5: = 0 fixed
b4: = 0 fixed
b3: = 0 Positive print
= 1 Negative print
b2: = 0 Does not follow m parameter
= 1 Follows m parameter
b1: = 0 Does not follow n parameter
= 1 Follows n parameter
Positive print associates to level 1 of the bit received the print of a dot and to the level
0 the non print; negative print does the opposite.
The decimal value of the m parameter defines the length of the print line, expressed in
number of points.
If the parameter has value 0 or is absent, the default condition is forced; its value
corresponds to the maximum number of points printable per line at the selected
density, minus any value of the left margin.
The decimal number of the n parameter defines, in elementary steps, the horizontal
position at which two consecutive dots can be printed.
If the parameter has value 0 or is absent, the default condition is forced (180 dpi).
