Apparatus and method for determining the page description language in which a print job is written
First Claim
1. A printing system for producing prints from a print job written in one of a plurality of page description languages with the print job assuming a form of a print job stream, comprising:
- a plurality of page description language analyzing units for sampling the print job stream, each analyzing unit outputting an information signal which provides information regarding the print job stream; and
a filter, receiving each of the information signals, for processing the information signals and outputting a filtered signal which indicates the page description language in which the print job is written, said filter including a set of rules for arbitrating conjunctively the information signals, the set of rules being dynamically configurable by a printing system user, said filter having a control line and said configuring including transmitting a control signal from the printing system user to said filter and, in response to receiving the control signal across the control line, said filter changing the set of rules so that said filter is provided with enhanced predictive capability.

Abstract
There is provided a printing system for producing 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 plurality of page description language analyzing units for sampling the print job stream, each analyzing unit outputting an information signal which provides information regarding the print job stream. A filter, 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.

10. A method of determining a page description language of a print job, the print job being written in one of a plurality of page description languages and assuming a form of a print job stream, comprising the steps of:
-
communicating the print job stream to a plurality of page description language analyzing units; generating a plurality of information signals from the plurality of page description language analyzing units, each of the information signals providing information regarding the print job stream; transmitting the information signals to a filter; and processing the information signals with the filter for generating a filtered signal that indicates the page description language in which the print job is written, said processing step including arbitrating conjunctively the information signals with a set of rules, the set of rules being dynamically configurable by a printing system user; said filter receiving a control signal from the printing system user and changing the set of rules, in response to receiving the control signal, so that the filter is provided with enhanced predictive capability. - View Dependent Claims (11, 12, 13, 14, 15)
