Abstract
An apparatus and method for setting authentication information of an information processing apparatus is provided. When a setting of a password to a PostScript (PS) interpreter is performed by a PS command, the password is stored in a volatile memory. When the setting of a password to the PS interpreter is performed through a setting screen, the password is stored in a nonvolatile memory, and thereafter, stored in the volatile memory.
Claims19
An information processing apparatus including at least one processor, a volatile storage device and a non-volatile storage device, wherein an interpreter of a page description language (PDL) command is loaded by the at least one processor, the information processing apparatus comprising:
- the at least one processor configured to:
- provide to the interpreter a first PDL command that is received from an external apparatus and that includes an instruction for setting first authentication information to the interpreter, wherein the first authentication information is authentication information for the interpreter to permit a change of setting of the interpreter, and the interpreter
- stores the first authentication information in the volatile storage device by interpreting the first PDL command;
- control a display to display a setting screen for enabling a user to input second authentication information to be set to the interpreter;
- store the second authentication information input through the setting screen in the non-volatile storage device;
- and
- each time the apparatus is powered on, read the second authentication information from the non-volatile storage device and generate and provide a second PDL command that includes an instruction for setting the read second authentication information to the interpreter unless the second authentication information is replaced with different authentication information, wherein the interpreter stores the second authentication information in the volatile storage device by interpreting the second PDL command.
A method for controlling an information processing apparatus including at least one processor, a volatile storage device and a non-volatile storage device, wherein an interpreter of a page description language (PDL) command is loaded by to at least one processor, the method comprising:
- provide to the interpreter a first PDL command that is received from an external apparatus and that includes an instruction for setting first authentication information to the interpreter for the interpreter to permit a change of setting of the interpreter;
- storing, by the interpreter, the first authentication information in the volatile storage device by interpreting the first PDL command;
- controlling a display to display a setting screen for enabling a user to input second authentication information to be set to the interpreter;
- storing the second authentication information input through the setting screen in the nonvolatile storage device;
- and
- each time the apparatus is powered on, reading the second authentication information from the non-volatile storage device and generating and providing a second PDL command that includes an instruction for setting the read second authentication information to the interpreter unless the second authentication information is replaced with different authentication information, wherein the interpreter stores the second authentication information in the volatile storage device by interpreting the second PDL command.
An information processing apparatus including at least one processor, a volatile storage device and a non-volatile storage device, wherein an interpreter of a PDL command is loaded by the at least one processor, the apparatus comprising:
- the at least one processor configured to:
- provide to the interpreter a first PDL command that is received from an external apparatus and that includes an instruction for setting first authentication information to the interpreter, wherein the first authentication information is authentication information for the interpreter to permit a change of setting of the interpreter, and the interpreter stores the first authentication information in the volatile storage device by interpreting the first PDL command;
- control a display to display a setting screen for enabling a user to input second authentication information to be set to the interpreter;
- store the second authentication information input through the setting screen in the non-volatile storage device;
- and
- based on powering on of the apparatus, read the second authentication information from the non-volatile storage device and generate and provide a second PDL command that includes an instruction for setting the read second authentication information to the interpreter.
