Note:
When no Fine Line Spacing is specified prior to an
activate command, the default spacing in the current
menu is activated.
To set lines per inch in multiples of 1/216 inch up to 255/216 inch, use this
command:
To execute a single line feed of 0.12 mm (1/216 inch) up to 29.98 mm
(255/216 inch) use this command:
Note:
For both these commands in Epson Mode n = 0-255.
The last code equals a number between 1 and 255. This line spacing
activates automatically when the printer receives this command.
For mechanical reasons, the printer advances paper in multiples of 1/144
inch, not in multiples of 1/216 inch, which is the standard for IBM printers.
To increase IBM compatibility, the printer multiplies the variable value
(01 to 255) by 2/3 to approximate 1/216 inch. Because of rounding off,
lines per inch slightly vary sometimes from the specified statement. For
more precise spacing, set lines per inch in multiples of 1/72 inch wherever
possible.
Automatic Skip Over Perforation
This feature specifies where the printer will skip from the bottom of one
page to the top of form of the next page. The printer automatically skips
over the perforation between pages of computer paper and starts printing
again at the next top of form. This feature can be used in a software
program, eliminating the need for inserting the programming command
for form feed (FF) after every page. After the automatic skipping distance
is set, long documents of several pages long can be printed without the
pages running together.
Before setting automatic skip over, it is a good idea to set the form length
and top of form. Although automatic skip over perforation of one inch can
be selected in the printer’s menu, the following command can vary the
distance skipped:
