Try it without a printer
Type something in and print. What comes out is what a real printer would put on paper.
A receipt is a stack of blocks. Turn one off and see what is left. The items and the total stay: without those it is not a receipt any more.
- Logo
- Business name
- Address and VAT number
- Date and receipt number
- The items
- Total
- VAT line
- How it was paid
- Closing line
The same call, a different template. A receipt grows with what is on it; a label is a fixed sheet and the text has to fit.
