Abstract
Abstract A printer attached to a computer using a driver routine includes an appropriate interface configured to receive, from the computer, an intermediate, device non-specific code such as a Page Description Language (PDL) message generated by an active printer driver routine and provide a corresponding bitmap. The computer may be a standalone workstation connected to the printer or a server providing printer services to a network of users. The printer also has a print engine configured to print an image corresponding to the bitmap. A communications interface is connected to receive a latest version of the printer driver routine which is then stored in a local memory that is part of the printer. The printer further includes a local processor for selectively supplying the computer with the latest version of the printer driver routine from the local memory. The local printer processor may be responsive to a version designation of the active printer driver routine (i.e., the routine installed in the client computer or local server) for selectively supplying the latest version of the print driver routine. The printer may be connected to the computer over a dedicated printer channel, such as a parallel or serial printer port. The communications interface for receiving updated driver routines may include connectivity to a wide area network, such as the Internet, to provide access to a centralized database of printer servers including the latest versions of the drivers.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
130 words
A printer, comprising: a communication interface; memory; and a processor for processing data received via said communication interface, wherein said processor, when operating under control of instructions stored on said printer, is operable to download a driver from a remote resource via the Internet utilizing said communication interface to store said downloaded driver in said memory, wherein said driver defines instructions for generating print messages for said printer and is associated with a first version identifier, said processor being further operable to parse a second version identifier from a print message when a client system communicates data to said printer via said communication interface, wherein said processor communicates said downloaded driver to said client system when said processor determines said second version identifier does not match said first version identifier.
Claim 2
Dependent Claim
130 words
A printer, comprising: a communication interface; memory; and a processor for processing data received via said communication interface, wherein said processor, when operating under control of instructions stored on said printer, is operable to download a driver from a remote resource via the Internet utilizing said communication interface to store said downloaded driver in said memory, wherein said driver defines instructions for generating print messages for said printer and is associated with a first version identifier, said processor being further operable to parse a second version identifier from a print message when a client system communicates data to said printer via said communication interface, wherein said processor communicates said downloaded driver to said client system when said processor determines said second version identifier does not match said first version identifier.
Claim 3
Dependent Claim
16 words
The printer of claim 1 wherein said print message is a page description language (PDL) message.
Claim 4
Dependent Claim
21 words
The printer of claim 1 wherein said print message is received when said client system communicates data to print a document.
Claim 5
Dependent Claim
38 words
The printer of claim 3 wherein said processor ceases generation of a bitmap image from data communicated by said client system for said document to be printed, when said processor communicates said downloaded driver to said client system.
Claim 6
Dependent Claim
30 words
The printer of claim 1 wherein said processor communicates a message to said client system to indicate that said downloaded driver is available, before said processor communicates said downloaded driver.
Claim 7
Dependent Claim
12 words
The printer of claim 1 wherein said remote resource is a database.
Claim 8
Dependent Claim
17 words
The printer of claim 6 wherein said database is accessible by said processor through a web site.
Claim 9
Independent Claim
86 words
A method of operating a printer, comprising: downloading a driver from a remote resource by said printer, wherein said driver defines instructions for generating print messages for said printer and is associated with a first version identifier; storing said driver in memory of said printer; receiving, by said printer, a print message from a client system; parsing a second version identifier from said print message; and communicating said downloaded driver to said client system when said second version identifier does not match said first version identifier.
Claim 10
Independent Claim
86 words
A method of operating a printer, comprising: downloading a driver from a remote resource by said printer, wherein said driver defines instructions for generating print messages for said printer and is associated with a first version identifier; storing said driver in memory of said printer; receiving, by said printer, a print message from a client system; parsing a second version identifier from said print message; and communicating said downloaded driver to said client system when said second version identifier does not match said first version identifier.
Claim 11
Dependent Claim
16 words
The method of claim 8 wherein said print message is a page description language (PDL) message.
Claim 12
Dependent Claim
21 words
The method of claim 8 wherein said print message is received when said client system communicates data to print a document.
Claim 13
Dependent Claim
35 words
The method of claim 8 further comprising: ceasing generation of a bitmap image from data communicated by said client system for said document to be printed, when communicating said downloaded driver to said client system.
Claim 14
Dependent Claim
27 words
The method of claim 8 further comprising; communicating a message to said client system to indicate that said downloaded driver is available, before communicating said downloaded driver.
