Reset (Operating Commands.); Aligment Tuning; Print Direction And Speed - DCA Intertel 2000 Technical Manual

4.2.1 RESET (OPERATING COMMANDS.)

ASCII:
decimal:
hexadecimal:
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

0 ≤ n ≤ 20, default value 0hex ≤ n ≤ 14hex).
This command allows for the fine tuning of the print head alignment during bidirectio-
nal print. The fine 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 verification can be performed
using the BASIC program that follows; fig 15 shows how alignment is affected by diffe-
rent values of "n". By changing the default value, fine 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

Comment:
n = 1 enables half speed printing
n = 0 restores standard full speed printing
