Problems solved by technology

When the job is reprocessed next time, due to the change of the context of the running environment, the data received again will change, and the error processed last time may not be able to reproduce and locate
This has greatly increased the difficulty of debugging and locating errors

Embodiment Construction

[0032] The embodiment of the present invention records the actual production process, so as to reproduce the actual production process, realize data playback, and capture errors occurred in the actual production process during the data playback process, so as to realize error location.

[0033] In the embodiment of the present invention, all data based on the Intelligent Printing Data Stream (IPDS) protocol is referred to as IPDS data, which includes content data and command data. Content data refers to data for rasterization processing. The command data refers to the data about the processing capability of the printing control device for rasterization processing, and mainly refers to the query request received by the printing control device, the response message returned, and the abnormal information actively reported by the printing control device. The errors in this embodiment include the inconsistency between the processing results and the expected ones, abnormalities occu...

Abstract

The present invention discloses a data playback method and a device to realize simulation under actual application environment and capture errors during data processing to modify these errors and improve data processing quality. The method includes steps below: A simulated IPDS host interface is connected with a print controller. IPDS data to be transmitted by the IPDS host will be obtained from all saved IPDS data interacted between the IPDS host and the print controller and then the data will be transmitted to the print controller. In addition, the present invention discloses a error capture method based on data playback and a device to fulfill two methods as above.

Description

technical field [0001] The invention relates to the field of computer and electronic technology, in particular to a data playback method and device. Background technique [0002] Intelligent Printing Data Stream (Intelligent Printer Data Stream, IPDS) data is a printing protocol and description language based on the IBM mainframe, and is a streaming printing data. Different from other printing description languages, the IPDS host needs to establish a direct connection with the printing device at the beginning of the printing operation, and obtain the corresponding processing capability and corresponding physical characteristics from the printing device, and send the corresponding processing capability and physical characteristics to the printing device according to the obtained processing capability and physical characteristics. Send IPDS data to be processed for printing. [0003] IPDS RIP is a software for rasterizing IPDS data. It generates print-related rasterized dot ...
