ESC V n1 n2 Bit-Mapped Graphics
Format: ESC V n1n2
Dec: 27 86 n1n2
Hex: 1B 56 n1n2
Function: Prints the next (n1*256 + n2) dotlines as bit-mapped
graphics. “n1n2” form a 16-bit binary number set, most
significant byte first. Used to print user-generated bit map
graphics across the width of the print head. After receipt
of this command, the printer will dump the binary data
supplied directly to the print head. As customary with bit
map data, a “1” bit indicates a dot is on, “0” bit indicates
the dot is off. Graphics printed in this manner must be the
exact width of the head in bits. Bit 7 of the first byte of
data received will print at the left-most dot on the head as
you view the head with the paper feeding away from you.
The printer will remain in bit map graphics mode until the
total amount of bytes necessary to fill “n1 n2” lines of
print have been received by the printer.
