EVFU Default
The default EVFU will be generated based on the current form length
and lpi setting under the following conditions:
▪
When the printer is initialized
▪
When either the forms definition or lpi setting is changed
▪
When the start EVFU load escape sequence ESC ] is immediately
followed by the end load sequence ESC \
▪
When the emulation is changed from P Series or Dataproducts, to
ANSI
The following chart shows how the default EVFU table is defined:

movement to the channel specified by the number formed by p1 and
p2. Valid channel numbers are in the range 1- 12.
0;1 - selects channel 1
0;9 - selects channel 9
1;1 - selects channel 11
Channel 1 is always used for TOF; channel 12 is always used for
vertical tab. When the channel number is greater than 12, the
program defaults to channel 1. If the table has not been loaded and a
channel command is received, it is ignored.
