+- **Is a desk printer required? (user, 2026-09-06)** No, in either policy. With *Pagesa në

+  prints the receipt and the booth Z carries the wash line — so the wash shift is offered but
+  reconciles nothing (a desk printer would sit idle). With *Pagesa në lavazh* the till's Z and
+  vouchers exist and prefer the desk printer, but fall back to the booth's; printing is
+  best-effort, the signed event is the record. Where a desk printer becomes genuinely
+  required is a piece that does not exist: a **customer receipt at bay payment** (today the
+  customer gets nothing on paper). If built, it prints on the desk only, no fallback, and
+  Setup should warn when the policy is bay payment with no `wash-desk` printer. Also open:
+  hiding the wash till section on the desk when the policy is booth payment.
