================================Live preview
Preview your ESC/POS commands.
Paste the raw ESC/POS your POS would send and vprinter decodes every control byte — alignment, sizing, bold, cuts — into the exact receipt that would have printed. The cryptic byte stream on the left becomes the paper on the right.
