Method and system for making invoice

Abstract

The invention relates to a method and a system for making invoices. The method comprises the steps that each slave terminal transmits the terminal number of the slave terminal, the electronic invoice numbers of invoices to be printed and invoice surface information to a master terminal; the master terminal takes the electronic invoice numbers of the invoices to be printed as an invoice number range of one roll of invoices to be printed and transmits the invoice number range to the tax controller of the master terminal; the master terminal transmits the invoice surface information to the tax controller of the master terminal; the tax controller obtains tax control codes according to the electronic invoice numbers and the invoice surface information of the invoices to be printed; the master terminal transmits the tax control codes to the slave terminals corresponding to the terminal numbers; and the slave terminals print the electronic invoice numbers, the invoice surface information and the tax control codes of the invoices to be printed onto the invoices. By adopting the technical scheme, under the condition of only one tax controller, more than two slave terminals can print invoices at the same time.

Description

technical field [0001] The invention relates to the field of invoices, in particular to a method and system for issuing invoices. Background technique [0002] In large bazaars, shopping malls, supermarkets and other places with relatively large consumption, a certain number of invoice self-service terminals are often set up to provide consumers with self-service invoice issuance services. Consumers only need to provide them with the name of the merchant and the consumption items. , consumption amount, consumer name and consumption time and other face information, the self-service terminal can automatically print out the corresponding invoice. Compared with manual invoice production, the use of the invoice self-service terminal greatly shortens the time for consumers to print invoices. [0003] Our country has the following regulations on invoices: each invoice must have a tax control code as an anti-counterfeiting label, which is used to verify the authenticity of the invoi...

Problems solved by technology

However, in the prior art, each invoice self-service terminal is equipped with a tax controller. If multiple invoice self-service terminals are installed in one place, multiple tax controllers will inevitably be introduced, which violates the usage of tax controllers. limit

In addition, since each invoice self-service terminal is equipped with a volume of invoices to be printed, the volume of invoices to be printed has its own unique invoice number segment to be printed, which is used as a collection of invoice numbers of all invoices to be printed in the roll of invoices to be printed, each invoice The self-service terminal can only print invoices whose invoice numbers belong to its own invoice number segment to be printed, but cannot print invoices with other number segments. Terminal No. 1 installs a roll of invoices to be printed, and the invoice number range to be printed is 101-200, so Terminal No. 1 can only print invoices with invoice numbers between 1-100, and Terminal No. 2 can only print invoices with invoice numbers between 101-200 invoices and cannot print other invoices

After the self-service terminal provides the tax controller with the invoice number segment of a volume of invoices to be printed, the tax controller must calculate the tax control codes of the invoices to be printed sequentially in order before starting to calculate the next volume of invoices to be printed Therefore, if only one tax controller is used to provide tax control code calculation services for more than two invoice self-service terminals, it will inevitably cause only one invoice self-service terminal to work at the same time, and other invoice self-service terminals cannot The problem of work, the effect is the same as that of setting up only one invoice self-service terminal to provide invoice printing service, which seriously affects the efficiency of the invoice self-service terminal, and also greatly reduces the speed of invoice printing, bringing consumers a lot of trouble in printing invoices. great inconvenience
