4.2.1 RESET (OPERATING COMMANDS.)
ESC @ Printer reset
Format:
ASCII: ESC @
decimal: 27 64
hexadecimal: 1B 40
Comment:
The printer is reset to the initial conditions and default settings. ASCII code 64 can re-
present different characters according to the national character set used and the code
could therefore appear with different symbols on the keyboard(see table 10)
4.2.2 Aligment Tuning
ESC # J n Bidirectional alignment tuning
Format:
ASCII: ESC # J n
decimal: 27 35 74 n
hexadecimal: 1B 23 4A n
Comment:
0 ≤ n ≤ 20, default value 0hex ≤ n ≤ 14hex).
This command allows for the ne tuning of the print head alignment during bidirectio-
nal print. The ne alignment is required when extended ASCII graphic characters are
used (from 176 dec to 223 dec)
These graphic characters are normally printed bidirectionally, unless when unidirec-
tional print is forced (ESC< and ESC U n commands). Graphics mode and NLQ mode
printing always take place unidirectionally. Alignment verication can be performed
using the BASIC program that follows; g 15 shows how alignment is affected by diffe-
rent values of “n”. By changing the default value, ne alignment tuning can be obtai-
ned for both printing directions. Resolution is 1/480” (0.053mm) for each “n” unit.
4.2.3 Print direction and speed
ESC s n Half speed enable/disable
Format:
ASCII: ESC s n
decimal: 27 115 n
hexadecimal: 1B 73 n
Comment:
n = 1 enables half speed printing
n = 0 restores standard full speed printing
