Messaging

Password Security

For inbound messages (messages to the printer), an optional password can
be specified. For those commands that require a password, the string is
checked against the printer's telnet password; the message is rejected if the
password does not match. For commands that do not require a password, the
string is ignored. Only commands that change printer setup requires a
password. For information inquiry commands a password is not required. By
default the NIC password is zero, or an empty string. To change the NIC
password, please refer to the Printronix Network Interface Card User's
Manual .

Example of setting a password through telnet:
>set user passwd root mypassword

Message Unique ID

This feature is supported by PXML version 2.0 or higher. For inbound
messages (messages to the printer), an optional requestID number can be
specified. The generated response message will have the same requestID
attached to it.
None of the unsolicited messages will have any requestID attribute. If the
request does not include any ID, the response will have the requestID of 0.
Label, job, and RFID messages are unsolicited and do not include requested
ID. The label and job responses use the job ID, not the requestID.
The requestID value in any command sent to the printer needs to be between
1 and 4294967294. An example of a request sent to the printer with a
requestID include:
<?xml version="1.0"?>
<pxml requestID="203">
</pxml>
Response coming from the printer:
<?xml version="1.0" encoding="UTF-8"?>
<pxml requestID="203">
</pxml>
