Printing connection method and device, electronic equipment and printer

Abstract

The invention discloses a printing connection method, device and equipment and a printer. The method comprises the following steps: establishing first connection with the printer through a first port on the printer, wherein the first port is allowed to establish connection with a plurality of electronic devices at the same time; initiating a query request to the printer according to the first connection so as to obtain printer state information returned by the printer based on the query request, wherein the state information comprises the connection condition of the second port; when it is judged that the second port is in the disconnected state, initialting a connection request to the second port of the printer so as to try to establish second connection with the printer, wherein the second port is only allowed to establish connection with one electronic device at the same time; and after the second connection with the printer is successfully established, sending printing data to the printer through the second connection. According to the invention, the printing experience in a multi-user scene is improved.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a printing connection method, device, electronic equipment and a printer. Background technique [0002] As a common computer output device, printers are widely used in people's work, study and life. When printing, the user connects his terminal device to the printer in a wired or wireless manner, that is, the printing data in the terminal device can be sent to the printer for printing. [0003] With the development of technology and the change of working life style, small portable printers are becoming more and more popular. Portable printers allow people to take them with them to print on the go. [0004] However, due to cost constraints, current portable printers are often difficult to have a large memory. In order to avoid the problems of insufficient memory and data loss caused by connecting multiple terminals at the same time, the current portable printers are often set t...

AI Technical Summary

Problems solved by technology

[0004] However, due to cost constraints, current portable printers are often difficult to have a large memory. In order to avoid the problems of insufficient memory and data loss caused by connecting multiple terminals at the same time, the current portable printers are often set to only connect to one terminal at a time. Terminal, which brings a lot of inconvenience when multiple people want to use a portable printer at the same time, and the user experience is not good
