Power-off recovery automatic continuous printing device for printer

Abstract

The invention discloses a power-off recovery automatic continuous printing device for a printer. The power-off recovery automatic continuous printing device adopts the modes of power supply detection, file queue storage and power supply recovery automatic continuous printing to realize the function of power-off recovery automatic continuous printing of the printer. The power-off recovery automatic continuous printing device is internally provided with a power supply, so that data can be stored by the device and automatically sent to the printer for printing in a normal mode; when external power supply is detected to be abnormal, the device enters a power-off mode to enable the printer to be powered off normally; and when the device detects power supply recovery, the device enters a recovery mode to enable the printer to be powered on normally and restart remaining printing tasks in a queue. By means of the power-off recovery automatic continuous printing device, damage to printer hardware caused by sudden shutdown of power failures of the printer is reduced, and meaningless operation of a user is reduced. The external device does not need to change an internal structure and a connecting line of the printer, and only needs to use original wiring connection of the printer, so that the product is simpler and more convenient to install, and is suitable for popularization and application of all ink-jet, laser and needle printers.

Description

technical field [0001] The invention belongs to the related technical field of electronic printers, and in particular relates to an automatic continuous printing device for power failure recovery used by printers. Background technique [0002] At present, ordinary printers need to be used under the continuous power supply state. When the power supply is suddenly interrupted, the printing will be interrupted, and after the power supply is restored, the printing will not restart. Although the Chinese patent published on June 15, 2018 No. 201711236132.4 An intelligent 3D printer power failure recovery system patent can perform power failure recovery, but it only supports power failure recovery of 3D printers, and does not support ordinary inkjet, laser and dot matrix printers, and its universality is poor. Contents of the invention [0003] The object of the present invention is to provide an automatic continuous printing device for printers when power failure is restored, so...
