Example Embodiment

[0023] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0024] Reference figure 1 , Scan the printer when the server program is initialized, get the list of printers, save this printer list in a structure array PrinterList, the data types contained in the structure are PrinterName, TaskNumber, TaskTime. PrinterName is used to store the name of the printer, TaskNumber is initialized to 0, and TaskTime is initialized to the current time. Compare the array elements in the structure array PrinterList with the printer list saved in the PrinterList table in the database. The existing printers remain unchanged in the table; the newly added printers are added to the PrinterList table; the original PrinterList table exists, but The printer table entries that do not exist in this scan are deleted from the PrinterList table to complete the function of updating the printer list, and synchronize the structure array Pr...

Abstract

The invention discloses a novel method and system for parallel printing dispatching. A host of a printing server is connected with a plurality of usable printers, and maintains a printer list; and the list is updated when the host is rebooted or some new printers are added. For realizing parallel printing of a document, a client side transmits a message, containing the number N of the printers applied for, to the server before printing; and then, the client side segments the document to be printed into print pages, and transmits the print pages to the printing server. After receiving the print pages transmitted by the client side, based on the number N of the applied printers, the printing server takes the page as a unit, and adds the printing tasks to a printing queue of the N dispatched printers by a certain strategy. The technical scheme of the invention is featured by making full use of the printing resource, being convenient for unified management and having high efficiency.

Description

technical field [0001] The invention belongs to the technical field of computer software design and development, and relates to a printing scheduling method and system, in particular to a novel parallel printing scheduling method and system. Background technique [0002] For a long time, the printer scheduling strategy has been using the traditional serial method, that is, taking the document as the printing unit, sending all the printed pages of a document to the printer sequentially, and the printer prints the document page by page in order. When there are multiple printers, this coarse-grained scheduling method cannot perform parallel scheduling of jobs, and cannot achieve high-efficiency printer operations; at the same time, the user specifies the usage mode of the printer, and cannot perform strategic automatic scheduling on multiple printers. It causes uneven use of printers, unreasonable use of printers, etc., resulting in problems such as reduced life of printers and...
