Printer ACK or Error Response

Some commands do not return an immediate response, in this case the
printer will send an ack message indicating that it received the request. For
example the status select requests will enable or disable a particular kind of
unsolicited message from the printer. After the printer receives this kind of
message sends an ack message to the host, indicating that the message was
received.
<?xml version="1.0" encoding="UTF-8"?>
<pxml>
</pxml>
If there is a syntax error in the XML request message, the following error
message is sent:
<?xml version="1.0" encoding="UTF-8"?>
<pxml>
</pxml>
Some of the error messages include: Invalid Element, Invalid Attribute, Invalid
Data, Invalid Password, and Command (not available for this printer model).
