Paper Instruction (PI) – Optional standard or inverted level EVFU or DVFU signal from the host
with
the same timing and polarity as the data lines. PI line sensing is controlled by printer configura
-
tion.
NOTE:
The PI line must be disabled (configuration option selected fr
om the contr
ol panel)
if
the host
computer does not drive or contr
ol the PI line. If the line is not contr
olled by the
host
and sensing is enabled, rapid paper slewing will occur
.
