Abstract
Abstract A decomposing apparatus is provided for use in a printing machine of the type adapted to receive a first set of information written in a printer page description language and a second set of information written in a printer page description language. The decomposing apparatus preferably includes: an arrangement (60) for parsing the first set of information into a first set of image related components during a first time interval and the second set of information into a second set of image related components during a second time interval; and, an arrangement (94) for performing image related operations on selected components of the first set of image related components, the image related operations being performed on the first set of image related components during the second interval so that the image related operations can be performed on the first set of image related components substantially concurrently with the second set of information being parsed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
101 words
A printing machine for printing a job written in a printer page description language having information, the job information being decomposed into a printable form, characterised by parsing means (60) for parsing the information into image related components; means (94), separate from said parsing means (60), for performing image related operations on selected ones of the image related components, and means (24), defining a database and communicating with both of said parsing means (60) and said performing means (94), for storing identifiers representative of the image related components; and input means (25) for inputting the job to said parsing means (60).
Claim 2
Dependent Claim
149 words
A decomposing apparatus for use in a printing machine of the type adapted to receive a first set of information written in a first printer page description language and a second set of information written in a printer page description language, characterised by parsing means (60) for parsing the first set of information into a first set of image related components during a first time interval and the second set of information into a second set of image related components during a second time interval; and means (94) for performing image related operations on selected components of the first set of image related components, the image related operations being performed on the first set of image related components during the second interval so that the image related operations can be performed on the first set of image related components substantially concurrently with the second set of information being parsed.
Claim 3
Dependent Claim
29 words
A decomposing apparatus as claimed in claim 2, further comprising storing means (24), coupled to said parsing means, for storing the first and second sets of image related components.
Claim 4
Dependent Claim
38 words
A decomposing apparatus as claimed in claim 2 or claim 3, in which each set of information comprises global information and page-level information, wherein said parsing means comprises a processor (68) for distinguishing global information from page-level information.
Claim 5
Dependent Claim
91 words
A parser adapted to be used in a decomposing apparatus for a printing machine of the type adapted to receive a job written in a printer page description language, the job including global information and page-level information, characterised by a first processor (68) for splitting the job into the global information and page-level information, a second processor (70), coupled with said first processor (68), for parsing the page-level information into a set of image related components; and storing means for storing the image related components for use in printing the job.
Claim 6
Dependent Claim
32 words
A parser as claimed in claim 5, in which the job includes a plurality of pages, wherein the first and second processors (68,70) are adapted to operate on different pages substantially concurrently.
Claim 7
Dependent Claim
121 words
A decomposing apparatus for use in a printing machine of the type having a font storage section and being adapted to receive a set of information written in a printer page description language, characterised by parsing means (60) for parsing the set of information into a set of image related components, said parsing means including means for designating each of the the image related components with an image identifier, at least one of the image identifiers being a font name for a corresponding font; means (94) for performing image related operations on selected components of the set of image related components, said performing means determining whether the corresponding font for the font name is available in the font storage area (78).
Claim 8
Dependent Claim
62 words
A decomposing apparatus as claimed in claim 7, in which a second set of information written in the printer page description language is preparsed with the preparsing means (60), wherein the performing means (94) determines whether the corresponding font for the font name is available in the font storage area (78) substantially concurrently with the preparsing of the second set of information.
Claim 9
Dependent Claim
48 words
A decomposing apparatus as claimed in claim 7 or claim 8, further comprising parsing means (104) for mapping a font available in the font storage area (78) with the corresponding font of the font name when the corresponding font is not available in the font storage section (78).
Claim 10
Dependent Claim
121 words
A decomposing apparatus of the type adapted for use in a printing machine with a raster image storage section and an input for receiving a set of information written in a printer page description language, characterised by parsing means (60) for parsing the set of information into a set of image related components, at least one of the image related components being a raster image, the raster image being stored in the raster image storage section; means (94) for performing image related operations on selected components of the set of image related components; and means, communicating with the performing means and the raster image storage section, for processing the raster image in response to receiving a signal from the performing means.
Claim 11
Independent Claim

A method of decomposing for use in a printing system of the type having an input device adapted to program a job with global information and page-level information, characterised by programming the job at the input device with global information and page-level information; communicating the job to a first processor (68) of a parser (60); splitting the job into the global information and the page-level information with the first processor (68); passing the page-level information to a second processor (70); and parsing the job with the first and second processors (68,70) to create image related components.
Claim 12
Independent Claim

A method of decomposing a printer page description language for use in a printing machine, including parsing a set of information into a set of image related components; performing image related operations on selected components of the set of image related components; editing the image related components; and outputting the edited image related components to a marking engine.
Claim 13
Independent Claim
117 words
A method of decomposing for use in a printing arrangement of the type having a section for storing a job including information written in a printer page description language and a decomposer adapted to place the job in a suitable form for printing on a marking engine, comprising the steps of: inputting the job to the decomposer for decomposition when the decomposer is ready for the job; storing the job in the storage section when the decomposer is not ready for the job; and holding the job in the storage section until the decomposer is ready for the job so that the job can be decomposed, in accordance with the inputting step, when the decomposer is ready.
