Configuring The LQ-1600K Emulation With Control Codes
Line Feed
ASCII Code LF
Hex Code 0A
Dec Code 10
Purpose Prints the data in the buffer (if any) and advances the vertical
character position a distance of one line at the current line
spacing.
Comment If configured for LF equals newline (LF=CR+LF), the simulated
print head is moved to the left margin, otherwise it is not moved
from its current position. The current line is printed, and the
simulated printhead moves down a distance equal to the
current line spacing. If there are no dots, the paper is moved
but no printing occurs. When possible, successive line feeds
are accumulated and moved at once. The amount of paper
advanced by the LF code can be set by any of the line spacing
control codes: ESC 0, ESC 2, ESC 3, ESC A, or ESC +.
This code cancels all single line print attributes such as double
high and double wide characters.
Line Feed n/180 Inch
ASCII Code ESC J n
Hex Code 1B 4A n
Dec Code 27 74 n
Purpose Immediately advances the paper n /180 inch.
Where:
n = 0 through 255
Comment
n
= 0 is ignored. This command produces an immediate line
feed but does not affect line spacing or produce a carriage
return. Any one-line-only print attributes in effect are canceled.
Small values of n may result in overlapping lines. Overlapping
lines may also occur if print attributes such as double high,
superscript, or subscript characters are used on the same line.
Example The following example illustrates n /180-inch line spacing.
