Graphics: 5 Dot
Enters or exits graphics printing mode which prints only the top five dots of the
column (corresponding to the top five wires of the printhead). These top five
dots correspond to the least significant five bits (bits 0-4) of the data sent to the
printer as shown in the table.

Use the following characters to define the graphics (least significant five bits):
•
Hexadecimal: 20-3F
•
Decimal: 32-63
•
ASCII: SP-?
Each byte of data sent defines each column of the graphic to be printed. The
first byte defines the column in the left margin, with the following bytes
defining the columns to the right, for a total of up to 200 columns in the print
line. The print line is printed unidirectionally. Graphics and text may be printed
on the same line.
Use three Vertical Tab commands (0B) to overlap printing by half a dot with the
next line. Each vertical tab advances the paper by 0.02083 inches, with three
tabs advancing the paper by 0.062 inches.
Note: This command provides compatibility with earlier model printers. It
is generally not used for new applications. See the Graphics
command (1E) for the more generally used command.
