some cases, the printer may have to engage brake frequently waiting for next
command resulting in trembling. When this switch is set to OFF, the printer
starts printing only when more graphical data from Windows driver are
collected thus performing a much smoother printing operation.
Switch position 2 is usually set to OFF for use with 80 mm paper width.
When the printer is installed with the 58 mm paper spacing plate for use with
the paper roll of 58 mm width, the switch should be set to ON.
Switch position 3 is usually set to OFF for ESC/POS command
application that prints at 512 dots / line. Only technical users shall set this
switch to ON and make the printer work in the 576 dots / line format.
The switch position is recommended to set to ON when the optional
spill protect cover is used. In this way, the printer performs an automatic paper
cut each time the top hood is closed (e.g. after paper roll loading) with the
printer in operating condition. However, when there is no spill protect cover, it
is recommended to set to OFF and the manual cutter can be engaged whenever
necessary.
MULTIPLE INTERFACE ISSUE
For model PP-8000, there are 2 connectors for host connection through
RS232 or parallel. For PP-8000U, there are 3 connector for host connection:
RS232 and parallel in addition to the USB port. Please always connect
only
one interface at a time
. Simultaneous multiple host connections could result
in unexpected results!
UPOS CONCERNS
The UPOS compliance and WEPOS compliance ability of the PP-8000
series dictates the printer to perform certain internal affairs such as counter
refreshment periodically. When the printer is engaged in such operations there
will be a brief period of time that the printer is busy without externally
apprehensible cause. In other words, the printer will lit the ERROR LED
briefly once in a while even when no external communication is in process and
that is definitely normal.
