How to use it

Paste the script

Check text, barcodes, coordinates, size, and obvious risks.

Confirm before real printing

Preview reduces test prints, but final validation still belongs on real hardware.

ESC/POS Receipt Preview FAQ

No. It gives a readable receipt draft so you can review alignment, text, and command order before using the target POS printer.

The tool reads pasted ESC/POS escape sequences, text lines, alignment commands, and cut commands for quick debugging.

Code pages, printer width, font mode, cutter support, cash-drawer wiring, and vendor-specific ESC/POS extensions can change the final receipt.

ESC/POS receipt preview workflow

ESC/POS output is a stream of bytes, not a page layout language. Preview helps identify alignment, text, feed, and cut commands before testing a receipt printer.

Start by decoding visible text and common control commands such as initialize, align, feed, and cut.

Check whether the problem is layout, code page, paper width, or device-specific cash drawer behavior.

Use sample receipts when reporting POS bugs so private customer data is not shared.

Confirm final output on the target printer model because command support varies by firmware.
