System and method for evaluating control card for printer

Abstract

The invention discloses a printer control card evaluating system: the control card receives printed data from a computer and makes explanation, bus protocol conversion and other processing on the printed data and transmits the obtained data to a simulator, the simulator makes protocol conversion on this data and then inputs the converted data into the computer; the computer explains its own printed data and applies the explained data and the data from the simulator to evaluate the control card. The invention also discloses a printer control card evaluating method, making the control card receive printed data of a computer and make explanation, bus protocol conversion and other processing on the printed data, where the obtained data can be processed by bus protocol conversion again and then the converted data is inputted into the computer; and the computer receives this data and then applies this data and the data obtained by explaining its own printed data to evaluate the control card. The invention can remarkably improve control card evaluating efficiency and accuracy.

Description

technical field [0001] The invention relates to computer technology, in particular to an evaluation system and evaluation method of a printer control card. Background technique [0002] Currently used printers mainly include two hardware devices: one hardware device is a control card, and the other hardware device is a core. Among them, the control card is an embedded signal processing card, which is usually inserted into the upper control card slot of the machine core and connected with the machine core through a data interface; in addition, the control card is also connected with the computer, and the connection between the control card and the computer The data interface between them is usually a parallel port, a USB Universal Serial Bus (USBUniversal Serial Bus) interface, a network port, and the like. The control card is used to receive the print data from the computer that supports the computer bus protocol, and interpret the print data and convert the bus protocol, s...

AI Technical Summary

Problems solved by technology

For example: if there should be horizontal and vertical lines printed on a certain test page, but the operator finds that there is a line segment misalignment or a small arc in the final printed line, the operator thinks that the control card 102 is not working properly or the working quality is poor. Low; if the distance between characters to be printed on each line of a certain test page is 2 cm, and the operator finds that the distance between characters in a certain line that is finally printed is not 2 cm, the operator will also think that the control card 102 is not working properly. Normal or low quality work

[0014] It can be seen from the above that the evaluation work of the control card 102 is carried out manually, and it takes time to print out the test page, so the evaluation efficiency is very low

In addition, the problems in the printed test page may not be or not only caused by the abnormal operation of the control card 102 or the low quality of the work, but because the mechanical vibration or response lag of the core 103 during printing, That is: the problems in the test page may also be related to the current working quality of the movement 103

This makes it difficult for the operator to accurately evaluate the current working quality of the control card 102 and whether the control card 102 works normally by observing the printed test page
