Add the rongta PrinterDevice driver (ESC/POS over raw TCP 9100) and the device-agnostic pieces around it: - Roles + failover: each printer declares a role (entry-dispenser/booth- receipt) and failoverRank; printer-routing.ts picks the best healthy printer and falls back outside->booth for entry tickets (never the reverse). - Live status: MonitorableDevice.readStatus()/PrinterStatus capability. The Rongta driver scrapes the device's own /prn_stat.htm (Cover/Cutter/Paper End/Near End/Off-Line) rather than hand-decoding DLE EOT, whose reply bytes on this clone don't match the canonical ESC/POS bit layout (verified on hardware) -- avoids a false-healthy. Maps to ready/degraded/offline, fail safe on an unreachable or unexpected page. - Server PrinterMonitor polls enabled printers (PRINTER_POLL_MS, default 5s), caches latest, emits "printer-status" on change. Exposed via GET /api/printers/status and an SSE stream for the booth UI. Verified against 10.0.10.6: ready when healthy, offline when unreachable (no throw), bus emits on change and suppresses unchanged reads. Wiki: new rongta-printer entity, printer-roles-failover and printer-status-monitoring concepts; BOM/index/log updated.

Reference BOM (recommended devices)
Reference bill of materials. Models to verify for local availability (Albania/EU); the payment terminal is dictated by the acquiring bank. (See parking-system-architecture §9.)
| Subsystem | Recommendation | Why |
|---|---|---|
| Barrier operator | Magnetic Autocontrol / FAAC / CAME / Nice | Owns physical safety in firmware (barrier-not-a-door) |
| Induction loops | Feig / BEA / EMX | Safety + free-exit detection |
| Access controller | dingtian-relay relay+input board | Decoupled inputs (host-in-the-loop); isolate the VLAN (network-isolation). (uhppote-controller/zkteco-controller rejected) |
| Permit readers | Nedap/Kathrein UHF, or Mifare → wiegand | Hands-free, or autonomous offline decisions |
| Casual identity | lpr-camera (Milesight, edge AI) | Plate = ticket + independent record |
| Ticket dispenser | rongta-printer 80mm (entry-dispenser role) | ESC/POS over raw TCP 9100; driver written |
| Booth printer | rongta-printer 80mm (booth-receipt role) | Receipts + backup for entry tickets (printer-roles-failover) |
| Payment | Bank-certified P2PE standalone terminal + cash drawer | Keeps the app out of PCI-DSS scope |
| Host machine | Fanless industrial PC + UPS + atecc608 | Reliability, power-loss safety, offline signing |
| Network | Managed VLAN switch, PoE+ | Isolate the open control protocol |
Open procurement-driving decisions live in open-questions (esp. lane topology, payment subsystem). Payment subsystem detail: a standalone certified terminal keeps PCI scope out of the application — open-questions #3.
