Line Spacing
Unless changed, the printer is normally set to print 6 lines per inch (LPI);
the distance from the bottom of one letter to the bottom of the one below
is 4.23 mm (1/6 inch). If more lines are required on a page, use the 8 LPI
command (3-mm (1/8 inch) spacing), or the 2.45 mm (7/72-inch) spacing.
The 8 LPI command is mostly used in 7-Bit Graphics.
Fine Line Spacing
For graphics or special effects, use the fine lines per inch commands,
which change the spacing in multiples of 1/72 inch or 1/216 inch. This
does not affect the height of characters; it changes only the spacing
between the lines. For example, if a fine lines per inch of 72/72 inch is
selected, there is 1 inch between the bottom of one line and the bottom of
the next. To set lines per inch in multiples of 1/72 inch, first use:
The last code "n" is the multiple you require and is a number with a
decimal value greater than 1 and less than 85.
For the Epson Mode that is all you need to do. For the IBM modes you
must also activate the lines per inch set using:
This command activates the fine lines per inch set by the CHR$(27);"A";
CHR$(1-85) command. These two commands are used to return to 6 LPI
by having CHR$(1-85) equal 12 (12/72 inch equals 1/6 inch line spacing.)
