Abstract

The invention discloses a printing method and device. The method comprises the following steps that: in a process that an operating system is connected with a printer, through an environment variableLD-PRELOAD, loading a libvrvhandler.so file, wherein the printer comprises a virtual printer and / or physical printer; through the libvrvhandler.so file, judging whether the printer is the virtual printer or not; and if the printer is the virtual printer, processing a printing task through the virtual printer. In the method, only in the process that the operating system is connected with the printer, the libvrvhandler.so file bound with the environment variable LD-PRELOAD in advance is loaded. Compared with the prior art that a process is under an operation state all the time, few system resources are occupied, and the use ratio of system resources is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a printing method and device. Background technique [0002] There are many types of printers, which can be divided into dot matrix printers, inkjet printers, laser printers, wax spray printers, thermal wax printers, and dye-sublimation printers according to the printing principle. Currently, the monitoring of printers is mostly realized through processes. [0003] In the process of researching the prior art, the inventor found that when the printer is monitored by a process, no matter whether the system starts the printer or not, the process is running all the time, resulting in a large overhead of system resources, and the user can find out and terminate it through the task manager This process makes the system lose control of the printer, thereby reducing the reliability of the printer's operation. Contents of the invention [0004] In view of this, an embodiment of the p...
