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.
