Embodiment Construction

[0062] Hereinafter, the present application will be described in detail with reference to the drawings and embodiments. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0063] When the merchant client uses multiple software with catering functions at the same time, the print services of multiple software with catering functions will use the same print port at the same time. When the print port is occupied by the print service, other print services The current printing port cannot be used, resulting in the inability of the printing service to continue to execute, for example, the failure to print or the preemption of the printing port between the printing services leading to deadlock and other problems.

[0064] Aiming at the problems existing in the current prior art, this embodiment provides a bill printing method, which can be applied to the client side, so t...

Abstract

The invention discloses a bill printing method and device, and relates to the technical field of printers, and the method comprises the steps that a printer service layer obtains a printing task according to a received printing request, and distributes the printing task to a corresponding printer virtual layer; the printer virtual layer monitors the available state of the corresponding printer physical layer according to the printer type information in the printing task to obtain a monitoring result about whether the printer physical layer is available or not; and controlling the printer physical layer to print the bill to be printed in the printing task according to the monitoring result. By means of the technical scheme, the technical problem that printing fails due to the fact that various kinds of software with the catering function request bill printing services at the same time can be solved, the situation that printing tasks fail and even deadlock (such as program jamming) is caused due to the fact that printing ports are preempted is effectively avoided, and user experience is improved.

Description

technical field [0001] The present application relates to the technical field of printers, in particular to a bill printing method and device thereof. Background technique [0002] With the popularization of computer communication technology and network, the bill printing function has become one of the core functions in many business scenarios, and the software with bill printing function is also widely used in large and small shopping malls to print shopping list receipts, financial cashier receipts, etc. . Most of the existing software with the receipt printing function adopts the method of "receiving the printing task—sending the task to the printer—executing the printing operation" to realize the receipt printing function. [0003] At present, the receipt printing in the catering industry is also gradually networked, especially the catering industry uses printers to print order receipts, etc. A large number of merchants usually use software with catering functions (for ...
