Abstract

In a printing device, when: a memory stores a conversion rule for converting a pre-conversion PJL command to a post-conversion PJL command; and a PJL command corresponding to the pre-conversion PJL command is received, a controller performs a PJL command execution process to convert the received PJL command to the post-conversion PJL command according to the conversion rule and execute a process based on the post-conversion PJL command. On a condition that a rule-targeting command to execute a rule-targeting process targeting the conversion rule is received via a LAN interface according to a first protocol not ensuring a prescribed level of security, the controller prohibits execution of the rule-targeting process based on the rule-targeting command. On a condition that the rule-targeting command is received via an interface different from the LAN interface, the controller performs the rule-targeting process based on the rule-targeting command.

Dependent claims

A printing device comprising:

a controller;
a memory;
a first communication interface;
and
a second communication interface,
wherein the controller is configured to perform:
when:
the memory stores a conversion rule for converting a pre-conversion printer job language (PJL) command to a post-conversion PJL command;
and a PJL command corresponding to the pre-conversion PJL command is received via the first communication interface or the second communication interface, a PJL command execution process to convert the received PJL command to the post-conversion PJL command according to the conversion rule and execute a process based on the post-conversion PJL command;
on a first condition including a condition that a rule-targeting command to execute a rule-targeting process targeting the conversion rule is received via the first communication interface, which is a local area network (LAN) interface, according to a first protocol not ensuring a prescribed level of security, prohibiting execution of the rule-targeting process based on the rule-targeting command;
and
on a second condition including a condition that the rule-targeting command is received via the second communication interface different from the LAN interface, the rule-targeting process based on the rule-targeting command.
