Description

Method, device, medium and equipment for changing drive file Technical Field The present invention relates to the field of driving technologies, and in particular, to a method, an apparatus, a medium, and a device for changing a driving file. Background In a conventional Linux/Unix-based operating system, after a print driver package is installed, a driver file is installed in a first path, which includes PPD (Printer Postscript Description) files describing printing device information. The PPD file may describe, for example, vendor information, functions, a mode of starting a driver, etc., and one PPD file corresponds to one device model. When a user adds a printing device, in order to match the correct driver, the printing system searches the PPD file matched with the corresponding model under the second path to generate a device icon for user interaction, and the user can set printing parameters or issue a printing job through the device icon. And a PPD file corresponding to the PPD file in the first path is also generated in the second path, and the content of the PPD file in the first path is consistent by default. And if the user changes the print parameters in the driver interface via the device icon, the operating system will make the same change to the print parameters in the PPD file of the second path. However, the operating system may not be able to successfully keep the content of the PPD file of the second path consistent with the PPD file of the first path in any case. Disclosure of Invention An object of the present invention is to solve the drawbacks of the prior art that a user cannot normally use a printing apparatus after performing a drive update in some cases. According to a first aspect of the invention, a method for changing a driving file is provided, and the method comprises the steps of responding to a first instruction, determining a preset attribute value of at least one first equipment characteristic description file in a first path, wherein the first path is used for storing a driving installation file, changing at least one configuration parameter in a second equipment characteristic description file which accords with the preset attribute value in a second path to be identical to the corresponding first equipment characteristic description file, and storing a system setting file in the second path. Preferably, the first instruction is executed after a software update command is triggered, where the software update command is used to update at least a first device feature description file in a first path, and does not make the same change to a second device feature description file corresponding to the first device feature description file in a second path. Preferably, the corresponding first equipment characteristic description file is a first characteristic description file with the same preset attribute value as the second equipment characteristic description file. Preferably, determining the preset attribute value of at least one first device feature description file in the first path includes reading and saving the preset attribute values of all the first device feature description files in the first path. Changing at least one configuration parameter in a second equipment characteristic description file which accords with the preset attribute value in a second path to be the same as the corresponding first equipment characteristic description file comprises traversing all the second equipment characteristic description files in the second path, and updating the configuration parameter in a first characteristic description file which accords with the preset attribute value in the second equipment characteristic description file in the first path and has the same preset attribute value as the second equipment characteristic description file into the second equipment characteristic description file. Preferably, before responding to the first instruction, the method further comprises the steps of judging that the triggered command is a software update command or a software deletion command, if the triggered command is the software deletion command, after the software deletion command is triggered, responding to the second instruction, determining a preset attribute value of at least one first equipment characteristic description file to be deleted in the first path, and deleting a second equipment characteristic description file conforming to the preset attribute value in the second path. Preferably, the method further comprises the step of changing at least one configuration parameter in the second equipment characteristic description file meeting the preset attribute value in the second path to be the same as the corresponding first equipment characteristic description file, wherein the step of generating a new second equipment characteristic description file based on the corresponding first equipment characteristic description file to replace the original second equipmen
