PRINTING DEVICE EXECUTING PRINTER JOB LANGUAGE COMMAND ON SPECIFIC CONDITION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18465282 titled 'PRINTING DEVICE EXECUTING PRINTER JOB LANGUAGE COMMAND ON SPECIFIC CONDITION

Simplified Explanation

The patent application describes a system in a printing device where a computer determines whether to execute a Printer Job Language (PJL) command based on the type of command and the communication interface through which it was received.

  • The computer prohibits the execution of a PJL command if it belongs to a certain type when received through a LAN interface.
  • The computer executes the PJL command if it belongs to a different type when received through a LAN interface.
  • When the PJL command is received through a different interface, the computer executes the command regardless of its type classification.

Potential Applications

This technology could be applied in various printing devices to control the execution of PJL commands based on their type and the communication interface through which they are received.

Problems Solved

1. Preventing unauthorized or potentially harmful PJL commands from being executed. 2. Ensuring proper functioning and security of the printing device by controlling the execution of PJL commands.

Benefits

1. Enhanced security and control over the printing device's operations. 2. Improved reliability and performance by selectively executing PJL commands based on their type.

Potential Commercial Applications

"Enhanced Control of PJL Commands in Printing Devices" could find applications in commercial printers, multifunction devices, and other printing equipment where security and control over PJL commands are crucial.

Possible Prior Art

One possible prior art could be systems that filter or block certain types of commands in networked devices to prevent security breaches or unauthorized access.

Unanswered Questions

How does the system classify PJL commands into different types?

The patent application does not provide details on the criteria or method used to classify PJL commands into different types for execution control.

What are the specific security risks associated with executing unauthorized PJL commands?

The potential security threats or risks posed by executing unauthorized or prohibited PJL commands are not elaborated on in the patent application.


Original Abstract Submitted

In a printing device, on a first condition including that a printer job language (PJL) command is received via the first communication interface that is a LAN interface, a computer performs prohibiting execution of the PJL command when the PJL command is classified into a first command type, and executing the PJL command when the PJL command is classified into a second command type different from the first command type. On a second condition including that the PJL command is received via the second communication interface different from the LAN interface, the computer performs executing the PJL command regardless of whether the PJL command is classified into the first command type or the second command type.
