Question: The A799II Ethernet printer will lockup with the OPOS test utility when I hot dock and
undock the unit, I get an error message when I try to print or claim the printer.
Answer: Hot docking / undocking is not supported on the Ethernet printer since A799II Ethernet
printer is not directly hooked up to the computer, Windows is not aware if the device is
present or not. When using the Ethernet printer it is recommend to OPEN / CLAIM the
network printer prior to printing a receipt and CLOSE the printer after the receipt is printed.
