Set up the receipt printer and cash drawer

The printer area ("Drucker" button in the header) supports three routes: USB (via the Windows printer list), network (IP address, port 9100 by default) and file (for testing).

Test print first

The test print checks connection, umlauts, cutting and the drawer without booking a receipt. Only print real receipts once it looks right.

Paper width and logo

Settings → Business & receipt lets you switch between 80 mm (42 chars) and 58 mm (32 chars) — the layout adapts. You can also set your own logo (PNG/JPEG); it prints black-and-white above the receipt header.

Cash drawer

The drawer is connected to the printer and opens automatically on cash payments (can be disabled). It stays closed for card and voucher payments.

If printing fails

A print error never breaks a booking: the receipt is booked and waits in the print queue. "Reprint now" appears in the printer area once the problem is fixed.
