The 2-year-old catering program has been running for more than 1 years in some restaurants.

For thermal-sensitive blade printers,

Use in supermarkets, restaurants and other needs of small tickets to print the occasion.

When you finish printing, the paper is automatically cut.

There is a typesetting problem, the alignment is not very strict.
