Narrow paper needs a purpose-built layout
Shrinking an A4 page until it fits a narrow roll makes text hard to read. Compact formats need a different arrangement rather than simple scaling. Salelog provides separate A4, 58 mm and 80 mm presentations.
A4 offers room for detail. Of the compact widths, 80 mm gives product names and values more space; 58 mm suits narrower paper with more wrapping.
Test the complete printing chain
Confirm the printer’s paper width. Create a sale with several products and long descriptions. Generate the matching PDF, inspect the preview and print it. Check margins, scaling, wrapping, contrast and cut position.
Bluetooth on the product box does not guarantee the same behaviour on every phone. Operating system, driver and manufacturer app all affect compatibility.
Printing is a choice, not a requirement
A digital PDF can be sent through an available channel and found again later. Paper may remain useful at a market stall or counter. Choose the method that fits the customer instead of printing by default.
Correct the transaction first
A polished layout cannot repair a wrong quantity or selling price. Amend the source operation and generate a fresh PDF. Make the current version clear if an earlier one was already saved.
