4.2.9 PAPER FEED
LF Line Feed
Format:
ASCII: LF
decimal: 10
hexadecimal: OA
Comment:
All data in the input buffer are printed and the sheet advances by one line. The length
of the actual fed paper is equal to the set line spacing.
ESC J n Advance sheet by n/216 inch
Format:
ASCII: ESC J n
decimal: 27 74 n
hexadecimal: 1B 4A n
Comment:
Paper advances by n/216 of an inch (1/216” = 0.118mm).
The range for “n” should be from 0 to 255 (OOhex...FFhex).
This command does not move the carriage to the beginning of the next line nor does
it affect subsequent lines: it can be seen as a means to obtain an immediate fractional
line feed with no carriage return for specic paper positioning purposes. If a perma-
nent fractional line spacing is required, command ESC 3 n should be used (see further
on).
ESC 0 Set line spacing to 1/8 inch
Format:
ASCII: ESC 0
decimal: 27 48
hexadecimal: 1B 30
Comment:
Line spacing is set to 1/8 of an inch (3.175 mm) for subsequent line feed commands.
It should be noted that value “zero” in the command sequence is the ASCII code zero.
(code 48 dec.)
ESC 1 Set line spacing to 7/72 inch
Format:
ASCII: ESC 1
decimal: 27 49
hexadecimal: 1B 31
Comment:
Line spacing is set to 7/72 of an inch (2.47 mm) for subsequent line feed commands.
