Method and apparatus for generating and printing a security stamp with custom logo on an electrophotographic printer
First Claim
1. A method for printing a security stamp using an image forming apparatus, said method comprising:
- (a) providing an image forming apparatus having a memory circuit for storage of data, a communications port, and a processing circuit;
(b) storing at least one security stamp bitmap in said memory circuit;
(c) upon receiving a print job through said communications port, rendering a page of said print job, and selecting one of said at least one security stamp bitmap; and
(d) printing said page with the selected one of said at least one security stamp bitmap.

Abstract
An improved electrophotographic printer is provided for generating a security stamp in firmware, and printing that security stamp to create documents that have a visible and tactile logo that is automatically printed on each page of a print job. The firmware will automatically create the proper bitmap of the security logo for a page'"'"'s print resolution and bit depth. Using a color laser printer, the security stamp can be printed using all of the process colors, such as CMYK, which would be rendered and printed at 400% toner coverage. This gives the security stamp a very dark visible appearance and a thick tactile texture. The security stamp can include an area for printing a serial number of the printer, and for printing a time and date stamp.

9. A method for printing a security stamp using an image forming apparatus, said method comprising:
-
(a) providing an image forming apparatus having a memory circuit for storage of data, a communications port, and a processing circuit;
(b) receiving security stamp image information through said communications port, and storing said security stamp image information in said memory circuit;
(c) generating at least one security stamp bitmap representation of said security stamp image information;
(d) receiving a print job through said communications port, rendering a page of said print job, and selecting an appropriate one of said at least one security stamp bitmap based upon at least one of said page'"'"'s (i) print resolution, and (ii) bit depth; and
(e) printing said page with the selected one of said at least one security stamp bitmap. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An image forming apparatus, comprising:
-
a memory circuit for storage of data;
a communications port that is effectively connected to said memory circuit and which can be effectively connected to at least one external device, and capable of transferring data therebetween;
a processing circuit that is configured to control the flow of data between said memory circuit and said communications port; and
a print engine that produces a physical output upon a print media under control of said processing circuit;
wherein said processing circuit is configured;
(a) to store at least one security stamp bitmap in said memory circuit;
(b) upon receiving a print job through said communications port, to render a page of said print job;
(c) to select one of said at least one security stamp bitmap; and
(d) using said print engine, to print said page with the selected one of said at least one security stamp bitmap. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
