Select character font
EscIn (27)(73)n <1Bh><49h>n
This command enables you to select a font and choose the print quality.
If n is set to 0 the printer's standard font and draft quality are selected.
If n is set to 2 the printer's standard font and letter quality are selected.
If n is set to 4 the download font (the characters you sent to the printer using the Esc =
command) and draft quality are selected.
If n is set to 6 the download font ( the characters you sent to the printer using the Esc =
command) and letter quality are selected.

This command enables you to define and download characters for printing.
Monospaced characters are designed on a grid eleven dots wide by twelve dots high. The
width of proportionally spaced characters is specified in n

.

and n

define the number of characters to be defined as follows: number of characters =
((n
1
+(n
2
*256)-2)/13.
n
3
is the character code of the first character in the sequence to be defined. It is assumed that
you are defining a sequence of characters whose code numbers increment by one for each
character to be defined.
If bits 1 and 2 of n
4
are 0 and bit 8 is set to 1, the bytes that make up the character definition
define the top eight rows of the grid, the most significant bit representing the top dot, and the
least significant bit representing the eighth dot down. Simply set a bit to 1 to print a dot in
that position on the grid, or to 0 to print white space.
