The application environment of the catering industry system has always had its own characteristics. As far as the use of printers is concerned, the most harsh environment is not the "back kitchen". After the customer orders the food at the front desk, the system transmits the menu information to the kitchen, and the chef prints the menu information through the connected printer to provide the customer with the food in a timely and accurate manner.
However, in the kitchen, the interruption of the network signal, power failure, paper change, and environmental noise caused the phenomenon that the menu was lost or wrong during the printing process, resulting in delay, omission or mistake on the order of the customer. The phenomenon of dishes and other issues causes unnecessary disputes and disputes, resulting in lower customer satisfaction. At the same time, frequent occurrences of lost orders and wrong orders directly lead to an increase in the maintenance cost of printing equipment.
In view of the application characteristics of the above-mentioned kitchen environment, Jiabo printer put forward a ticket-one control technology, which synchronizes the control through the upper layer software and the printer printing, ensuring the integrity of each ticket surface and effectively responding to signal interruption. Problems such as lost orders and wrong orders caused by power outages, complicated operating environments, etc.
This innovative ticket-specific print control technology has effectively solved the problem of lost orders and wrong orders in the catering enterprises' current kitchen printing, greatly reducing customer complaints and complaints; while improving customer satisfaction, effectively Reduce the maintenance cost of printing equipment for catering companies and system vendors.

Ticket control instructions
1. Definition of the ticket printing process
In page mode, the ticket printing process is defined as printing from the start of printing to the book surface.
In standard mode, the face-to-face printing process is defined as from the start of printing until the receipt of a cut-off command to perform a cut. The status of the printer during the ticket printing process is printing.
2. Description of the ticket control process
The upper control software and printer firmware complete the control of printing a ticket according to the following protocol:
1) First, the upper layer software needs to send 1B76 instruction to query the status return of the printer.
2) After receiving the command, the printer returns the current status of the printer.
3) The upper layer software determines the status of the printer. If the printer is in the normal state, it proceeds to step 4); if the printer is in the prohibition printing state, the upper layer software needs to determine whether the printer is in an error state. If it is in an error state, the upper layer software needs to wait for error recovery ( Manual recovery or automatic recovery), return to step 1).
4) The upper layer software sends a 1B78 instruction to query the status of the printer to return.
5) After receiving the command, the printer returns the status of the printer task.
6) The upper layer software determines the task status of the printer. If the printer is in the working state, return to step 4); if the printer is in the idle state, continue down.
7) The upper layer software issues a print job.
8) After the printer receives the print job, it interprets the instructions, processes the data, and starts printing.
9) The printer prints the ticket.
Repeat the process.
