P-Series Evfu Command And Channel Codes - Printronix P6000L User's Reference Manual

EVFU Memory Not Loaded - If the EVFU memory is not loaded, the printer will respond to
EVFU commands and channel codes sent from the host computer as a single line feed.
Paper Runaway Protection - If the EVFU memory is loaded and a channel code is sent that
was not previously loaded, the printer will move the paper a single line feed.
E Display - When the EVFU is enabled, E will be displayed on the control panel.
L Display - When the printer receives a valid load sequence, L will be displayed on the control
panel.
Channel Codes - The EVFU memory has the capacity for 132 line forms (22 inches maximum
length). The first line identification code (channel code) in the memory load program defines
the first line on the form; the second line identification code defines the second line on the
form, etc. The line identification codes used depends on the type of interface. No particular
sequence is required for the codes but each line must have a line identification code. Filler
channel codes are used for lines that will not be accessed by the print program. Any channel
code can be used as a filler except channel code 1 which defines the top-of-form. The same
filler channel code can be repeated as necessary for any number of lines.

P-Series EVFU Command and Channel Codes

The P-Series EVFU channel and command codes are loaded into the EVFU memory and
subsequently activated in one of two ways: by embedded ASCII codes in the data stream (PI
line disabled), or with the PI line and decoded interface data lines. Table 5-5 shows the EVFU
channel and commands when the PI line is used (enabled); Table 5-6 shows the EVFU chan
nel and commands selected with embedded ASCII codes when the PI line is not used (dis
abled). The channel and command codes are described as follows.
NOTE: Sensing the PI interface line is configuration controlled.
