Abstract

The application belongs to the technical field of printers and discloses a method and device for detecting bill printing state and a bill printer. The method for detecting bill printing state comprises the following steps: detecting the paper outlet angular velocity of the paper roll in the printer cartridge by a first sensor when the bill is printed; detecting a printing linear velocity of the bill by a second sensor when the bill is printed; calculating the radius of the paper roll in the printer cartridge according to the paper outlet angular velocity of the paper roll in the printer cartridge and the printing linear velocity of the paper roll when the bill is printed; the state of the printer paper roll is confirmed according to a radius of the paper roll in the printer cartridge.

Description

technical field [0001] The application belongs to the technical field of printers, and in particular relates to a detection method, a detection device and a receipt printer of a receipt printing state. Background technique [0002] Bill printing, including invoices, lottery tickets, various documents, etc. These bills are paper certificates for customers to protect consumer rights or business activities, and their integrity, clarity, and anti-counterfeiting are all indispensable elements. As a special equipment for printing, the receipt printer has strict requirements on the printing process and printing effect of the receipt printer. [0003] However, receipt printers often need continuous heavy-duty operations, and are prone to failures such as insufficient printing tape, but cannot detect and determine the status of the paper roll in the printer's paper compartment in time. Contents of the invention [0004] In view of this, the embodiment of the present application pr...
