EPOS [ESC] x <n> and/or [ESC] ! <n>

Description The [ESC] I <n> (e.g. capital “i”) command begins draft, large draft or

near letter quality print mode.

Where n 0 = 12 x 12 draft

1 = 12 x 14 large draft

2 = 24 x 16 near letter quality (NLQ)

3 = 24 x 16 near letter quality (NLQ)

4 - 7 repeats 0 - 3

Draft print modes are high-speed print modes intended to provide quality

print with minimal ink usage. The 12 x 12 draft font is the most efficient.

The 12 x 14 large draft font produces a larger more readable character

but with added ink usage. NLQ print mode is a two pass half-speed font.

It provides what is generally regarded as near letter quality print at

reduced speed with greater ink usage.

Note 1: In EPOS mode, [ESC] x <n> is similar to [ESC] I <n>. [ESC] ! <n>

performs a similar function; however, NLQ is not available.

Note 2: NLQ fonts cannot be rotated 90° or 270°.

Note

Switching from draft to NLQ modes causes the printer to print all

previously received information. Consequently, auto-center and right

justify do not print mixed draft and NLQ font as expected.
