Dual Density Bit Image Graphics Type 2 (ESC Y)

This control prints the supplied bit image data at 120 horizontal pel by 72 vertical
pel. Bit image data can be mixed with text data on the same line. Horizontally
adjacent dots are not allowed and will be removed if specified.
A two-byte count (LL HH) indicates the number of bytes that follow in this control.
LL is the least significant byte of the count; HH is the most significant byte. (The
number of bytes that follows should equal HH
X'0000', the control is ignored.
NN .. NN are the bytes containing the bit image data. The data format is in 8-bit
vertical slices, with the least significant bit the bottom dot and the most significant
bit the top dot. B'1' indicates a pel to be printed; B'0' indicates an unprinted pel.
Data that exceeds the right margin is discarded.

High Density Bit Image Graphics (ESC Z)

This control prints the supplied bit image data at 240 horizontal per by 72 vertical
pel. Bit image data can be mixed with text data on the same line.
A two-byte count (LL HH) indicates the number of bytes that follow in this control.
LL is the least significant byte of the count; HH is the most significant byte. (The
number of bytes that follows should equal HH
X'0000', the control is ignored.
NN .. NN are the bytes containing the bit image data. The data format is in 8-bit
vertical slices, with the least significant bit the bottom dot and the most significant
bit the top dot. B'1' indicates a pel to be printed; B'0' indicates an unprinted pel.
Data that exceeds the right margin is discarded.

Print All Characters (ESC \)

This control forces a specified number of characters to be interpreted as graphic
characters, including those that occur in the space normally reserved for controls.
A two-byte count (LL HH) indicates the number of bytes to be interpreted as
printable graphics. LL is the least significant byte of the count; HH is the most
significant byte. (The number of bytes that follows should equal HH
the count equals X'0000', the control is ignored.

Reverse Line Feed (ESC ])

This command causes the contents of the buffer to be printed and advances the
paper one line in the reverse direction from the paper path.
