Plotting Graphics (Rows)

Plotting Graphics (Rows)
Purpose Allows you to address and print any individual dot position using
odd and even dot plot commands. The odd and even dot plot
addresses each dot position using a row method (as opposed to
the column method created in Extended Graphics as described
on page 105).
Plotting Graphics (Rows) replaces the “Plot” command from IGP-
110/210/410.
Do not confuse the graphics plot command, (cc)Q, with the odd
dot plot command, (cc)Q, discussed below.The Graphics Plot
command is effective when an Extended Graphics Command is
selected and plots in vertical data bytes (columns). Odd dot plot,
described below, plots in
horizontal data bytes (rows) and is
effective when a Standard Graphics Command is selected.
Mode Graphics with a Standard Graphics Command selected
Format (cc)
plot data (cc)G
(cc) Represents the Special Function Control Code
(SFCC). Enter the specific SFCC for your Code V
configuration.
plot Represents a plot command. Enter Q for normal
density odd dot plot, or enter C for high density
even dot plot.
data The plot data. Enter the hex data required to
produce the desired graphics pattern. (See
Comments below.)
(cc)G Following the data, enter the (SFCC) for your Code
V configuration immediately followed by any valid
command character or G, the universal sequence
terminator.
Comments Graphics designed using this command can not be stored in
Code V memory for future use. Once your graphic pattern prints,
it is automatically purged from Code V working memory.
In typical plotting, the binary pattern ASCII characters supplied as
data are used to address the character columns with the Least
Significant Bit (LSB) corresponding to the left-most dot column.
The Code V, however, addresses the binary pattern of hex data
bytes in a “mirror image” of plotting, with the LSB addressing the
right -most dot position. Two plot types are available and defined
below: odd dot plot for normal density and even dot plot for high
density applications. You must define each byte of each data line
in plot format, which is explained in “Plot Data Byte Format” on
page 108.
Odd dot plot (normal density plotting) is selected with the Odd
Dot Plot command, (cc)Q
data (cc)G. Odd dot plot addresses the
odd numbered dot columns to produce a horizontal and vertical
density that varies based on the printer and mode of operation.
