Abstract
Abstract A method of combining data sets of heterogeneous image formats, such as PDL's. in a printing system. A first image data set is translated by a coprocessor, using an interpretation code among many stored in memory. In response to "end of job" data in the first image data set, the first image data set in a final image format is transferred to the memory, and a second image data set is transferred from the memory to the coprocessor. The image format of the second image data set is determined. An interpretation code for translating the second image data set is loaded into the coprocessor.

Claims Analysis

Claim 1
Independent Claim
203 words
In a printing system comprising a coprocessor adapted to translate image data according to an interpretation code, a memory for storing a plurality of interpretation codes and image data, and a guesser for determining an image format of a sample of image data, a method of combining data sets of heterogeneous image formats comprising the steps of: translating a first image data set of one image format including "end of job" data; in response to translating the "end of job" data in the first image data set, transferring the first image data set in a final image format to the memory, and transferring a second image data set of one image format from the memory to the coprocessor; determining the image format of the second image data set; loading to the coprocessor an interpretation code for translating the second image data set; translating the second image data set including "end of job" data; and in response to translating the "end of job" data in the second image data set, transferring the second image data set in a final image format to the memory so that the translated second image data set becomes continuous with the translated first image data set in the memory.

In a printing system comprising a coprocessor adapted to translate image data according to an interpretation code, a memory for storing a plurality of interpretation codes and image data, and a guesser for determining an image format of a sample of image data, a method of combining data sets of heterogeneous image formats comprising the steps of: translating a first image data set of one image format including "end of job" data; in response to translating the "end of job" data in the first image data set, transferring the first image data set in a final image format to the memory, and transferring a second image data set of one image format from the memory to the coprocessor; determining the image format of the second image data set; loading to the coprocessor an interpretation code for translating the second image data set; translating the second image data set including "end of job" data; and in response to translating the "end of job" data in the second image data set, transferring the second image data set in a final image format to the memory so that the translated second image data set becomes continuous with the translated first image data set in the memory.
Claim 3
Dependent Claim
68 words
The method of claim 1, further comprising the steps of: receiving in the memory a heterogeneous print job comprising a plurality of data sets, the data sets being in different image formats; transferring a first data set from the memory into the coprocessor; determining the image format of the first image data set; and loading an interpretation code for translating the first image data set to the coprocessor.
Claim 4
Dependent Claim
73 words
The method of claim 2, wherein the heterogeneous print job comprises a job ticket including a list of data sets in the heterogeneous print job, and further comprising the steps of: counting the number of data sets that have been translated by the coprocessor since the job was received; and in response to all of the data sets in the heterogeneous print job being translated, unloading the translated data sets from the memory.
