Abstract

Abstract A printing system produces prints from a print job written in one of a plurality of page description languages with the print job assuming the form of a print job stream. The printing system includes a page description language guesser (700) having a plurality of page description language analyzing units (702-1...702-N) for sampling the print job stream, each analyzing unit outputting an information signal which provides information regarding the print job stream. The guesser (700), which receives the information signals, processes the information signals and outputs a filtered signal which indicates the page description language in which the print job is written. The page description language (PDL) guesser must be able to identify a print job containing text written in any of the supported languages in order to enable multi-language simple text printing. The page description language (PDL) analyzing unit or units determines the position codes of the characters in the text of the data sample of the document and from the position codes determines the encoding method for the characters. If the characters are encoded in one of the supported encoding methods then the guessor sets the value of the PDL on that document to "Simple Text". Thus the PDL guesser can recognize text written in any language which can be expressed using a character set standard that can be encoded in one of the supported encoding methods.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 162 words
A printing system that distributes documents among a plurality of printers in a networked printing system comprising: a spooler (410) that receives documents and generates a print job from each document, a page description language guesser (700) having a plurality of page description language analyzing units (702-1...702-N) on said spooler, said plurality of page description language analyzing units for sampling a data sample from said document, said data sample including character sets of the text in the data sample of said page description language in which said print job is written, wherein said plurality of said page description language analyzing units analyze said data sample for said character sets to determine the encoding method of said page description language, and a supervisor (420) for forwarding said print job of said document from said spooler (410) to said one of said plurality of printers (422) for printing said document which can print said page description language of said print job of said document.
Claim 2
Dependent Claim 65 words
A printing system according to claim 1, wherein each of said page description language analyzing units (702-1...702-N) outputs a signal regarding said encoding method of said text of said data sample from said document, and further comprising, an arbiter (704) for receiving and processing said signals from said plurality of page description language analyzing units, said arbiter determining the page description language of said document.
Claim 3
Dependent Claim 56 words
A printing system according to claim 2, further comprising a binary filter for providing said arbiter (704) with an indication of a percentage of binary characters in said print job to prevent erroneously indicating that said print job is written predominantly in one page description language when it is written predominantly in another page description language.
Claim 4
Independent Claim 126 words
A method for distributing document printing among a plurality of printers in a networked printing system comprising: receiving documents at the networked printing system, generating a print job from each document by a spooler (420), sampling a data sample from said document, analyzing said data sample by a page description language guesser (700) having a plurality of page description language analyzing units (702-1...702-N) for character sets of text of said page description language to determine the encoding method and from said encoding method determining said page description language, and forwarding said print job of said document to said one of said plurality of printers (422) for printing said document which can print said page description language of said print job of said document by a supervisor.
Claim 5
Dependent Claim 62 words
A method according to claim 4, wherein the step of analyzing said data sample includes receiving and processing signals from said plurality of page description language analyzing units by an arbiter (704), said arbiter determining the page description language of said document and setting an attribute for said document to indicate the page description language for said print job of said document.
Claim 6
Dependent Claim 59 words
A method according to claim 5, wherein the step of determining the page description language includes providing said arbiter (704) with an indication of a percentage of binary characters in said print job to prevent erroneously indicating that said print job is written predominantly in one page description language when it is written predominantly in another page description language.
