Abstract

Securing printing systems and methods include a printer with a controller coupled to a memory and configured to perform a printer operation. The printer controller receives an instruction comprising a first font element and a second font element. An identifier corresponding to the second font element is retrieved from a memory. The printer generates and prints a graphical character that based on the first font element and an augmented symbol corresponding to the identifier.

First claim

1 - 20 . (canceled)

21 . A method for operation of a printer, the printer comprising a controller configured to perform a printer operation, the method comprising:
receiving, by the controller, an instruction comprising a first font element and a second font element, the first font element including incomplete font data for a font to be used for printing and the second font element including an address associated with an identifier; retrieving, from an external device via a network, the identifier corresponding to the second font element based on the address; augmenting the first font data based on a volatile determinant corresponding to the identifier to generate complete font data; generating, by the controller, a graphical character based on the complete font data; and printing, by the printer, the graphical character.

22 . The method of claim 21 , wherein a location of the identifier on the external device is identified by the address.

23 . The method of claim 22 , wherein the address is at least one of a memory address and a network address.

24 . The method of claim 21 , further comprising performing, by the controller, an authentication protocol with the external device.

25 . The method of claim 21 , wherein the first font element includes information about a font typeface, spacing, orientation, bitmap, height, pitch, or weight of the graphical character.

26 . The method of claim 21 , wherein the volatile determinant comprises information about a font typeface, spacing, orientation, bitmap, height, pitch, or weight of the graphical character, wherein the information is determined based on information associated to the identifier.

27 . The method of claim 21 , wherein the retrieving is performed over a communication interface by a communication protocol.

28 . A kiosk, comprising:
a user interface configured to receive a user action that causes a printing action; and a printer, including:
a printing device; and
a control circuit configured to, in response to the printing action, receive a first font element and a second font element and performing a printing operation, the first font element including incomplete font data for a font to be used for printing and the second font element including a memory address associated with an identifier, the control circuit configured to:
retrieve the identifier from the memory address based on the second font element;
augment the first font element based on a volatile determinant corresponding to the identifier to generate complete font data;
generate a graphical character based on the complete font data; and
transmit an instruction to print the graphical character to the printing device.

29 . The kiosk of claim 28 , wherein a location of the identifier on the external device is identified by an address.

30 . The kiosk of claim 29 , wherein the address is at least one of a memory address and a network address.

31 . The kiosk of claim 28 , further comprising performing, by the controller, an authentication protocol with the external device.

32 . The kiosk of claim 28 , wherein the first font element includes information about a font typeface, spacing, orientation, bitmap, height, pith, or weight of the graphical character.

33 . The kiosk of claim 28 , wherein the volatile determinant comprises information about a font typeface, spacing, orientation, bitmap, height, pitch, or weight of the graphical character, wherein the information is determined based on information associated to the identifier.

34 . The kiosk of claim 28 , wherein the retrieving is performed over a communication interface by a communication protocol.

35 . A system for authentication a document, comprising:
a remote server communicably coupled to a network that stores an identifier; and a printer, comprising:
a printing device; and
a control circuit configured to receive a first font element and a second font element and performing a printing operation, the first font element including incomplete font data for a font to be used for printing and the second font element including a memory address associated with the identifier, the control circuit configured to:
retrieve the identifier from the memory address based on the second font element;
augment the first font element based on a volatile determinant corresponding to the identifier to generate complete font data;
generate a graphical character based on the complete font data; and
transmit an instruction to print the graphical character to the printing device.

36 . The system of claim 35 , wherein the memory address is a location in a memory of a peripheral device.

37 . The system of claim 36 , further comprising performing, by the controller, an authentication protocol with the peripheral device.

38 . The system of claim 35 , wherein the identifier includes at least one of a printer name, a serial number, a MAC address, and an authentication key corresponding to the printer.

39 . The system of claim 35 , wherein the first font element comprises information about a font typeface, spacing, orientation, bitmap, height, pitch, or weight of the graphical character.

40 . The system of claim 35 , wherein the volatile determinant comprises information about a font typeface, spacing, orientation, bitmap, height, pitch, or weight of the graphical character, wherein the information is determined based on information associated to the identifier.
