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.
