Plot Data Line Format
267
3. Send a line terminator, either a Line Feed (LF, hex 0A) or a Form Feed
(FF, hex 0C). A Carriage Return (CR) may also be used instead of the LF
code, provided the Carriage Return has been configured for Carriage
Return =Carriage Return +Line Feed (CR =CR +LF).
a. A line feed (hex 0A) used as the line terminator plots the contents of
thebu ffer and advances the paper position a single dot row, based on
the vertical density of the current mode.
b. A form feed (hex 0C) used as the line terminator plots the contents of
the buffer and advances the paper to the next TOF.
4. Regardless of which line terminator code is sent, the emulation defaults to
the previously selected print mode unless further plot control codes are
provided with the data.
Double Density Plot
For double density plot, the plot line contains: Control Code hex 04, plot data
bytes, a Line Terminator (hex 0A or hex 0C), Control Code hex 05, plot data
bytes, and a Line Terminator. The control sequence for sending P-Series
Double Density Plot is:
1. Send the even dot plot control code EOT (hex 04), followed by plot dat a
bytes.
2. Send a line terminator, which causes the emulation to plot the data bytes;
the paper position is not advanced in Double Density Plot; the emulation
now waits for the second plot command and plot data bytes.
3. Send the odd dot plot control code ENQ (05 hex) and a second line of
data, followed by a line terminator.
a. A line feed (0A hex) used as the line terminator plots the contents of
thebu ffer and advances the paper position a single dot row, based on
the vertical density of the current mode. A CR (if CR =CR +LF is
configured) may also be used with the same result.
b. A form feed (0C hex) used as the line terminator plots the data bytes
and advances the paper position to the next TOF.
4. Regardless of which line terminator code is sent, the emulation defaults to
the previously selected print mode unless further plot control codes are
provided with the data.
