Question: Why my GDI printer does not work with the
AV260C?
Answer: Disable the Auto Scan function in the
application, then your printer will function in
normal working condition.
Question: Why some parallel port devices and software’s
keypro do not work with the AV260C?
Answer: The AV260C can do pass-through printing all
right , but the pass-through printing may not
work if you connect the parallel port with
devices other than printer. Therefore, if you
would like to connect some parallel port devices
other than printer, please do not connect them to
the same parallel port that AV260C currently
uses. It is suggested to use other parallel ports
to connect these devices or keypro. For
instance, you can connect the AV260C to LPT1,
and connect other parallel port devices to LPT2.
Or you can add a data switch to avoid the
problem.
