Embodiment Construction

[0048] In order to solve the problem that the virtual printer cannot take advantage of the advanced features and custom features of the printer, in the embodiment of the present invention, a method and device for semi-virtualized printing are proposed, which acquires the data to be printed based on the printing task submitted by the user; Verification of business-related information, confirming that the printing operation is performed when the verification is successful. Since the real printing driver is used to initiate the printing task, and the real printing driver communicates with the hardware and finally outputs it, all the characteristics of the printer can be retained.

[0049] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0050] refer to figure 2 As shown, in the embodiment of the present invention, the specific process of paravirtualized printing is as follows:

[0051] Step 200: Ob...

Abstract

The invention relates to the field of computers, and discloses a para-virtualization printing method and device. The method and device are used for solving the problem that a virtual printer cannot achieve the advanced features and self-definition characteristic of the printer. According to the scheme, the method comprises the steps that initial data to be printed are obtained based on a printing task submitted by a user; a real printer driver is called to obtain relevant printing parameters, format processing is carried out on the initial data to be printed based on the relevant printing parameters, and the data to be printed are obtained; printing operation is executed according to the data to be printed. Due to the fact that the real printer driver is used for initiating the printing task, and is in communication with hardware for final output, all characteristics of the printer can be kept.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for paravirtualized printing. Background technique [0002] Virtual printing technology is to use software in the operating system to simulate a real printer. Virtual printing is to select a virtual printer in the editing software and use the driver of the virtual printer to output the document in the editing software as a layout file. For example, in In editing word, use the "Adobe PDF" virtual printer to convert doc documents into pdf documents. Specifically, the user selects a virtual printer to initiate a printing task, and the printed content is sent to the virtual printer software through the processing of the printing pool. After that, the virtual printer generates a pdf file according to the customized function. [0003] The conversion between document formats is generally completed by printing with a virtual printer, but during the printing process, since t...
