Interface: PrinterTransport

Defined in: shared/peripherals/transport.ts:9

The seam every printer transport implements — WebUSB and raw TCP today, QZ Tray / Web Serial later. Transports move bytes; they never know about receipt content or ESC/POS dialects (that's the encoder's job).

ReturnsCopy Anchor Link

Promise<void>

queryStatus()?Copy Anchor Link

optional queryStatus(): Promise<PrinterStatus>;

Defined in: shared/peripherals/transport.ts:19

Optional — only transports with a read channel implement it (TCP via DLE EOT today). Absence means "status unknowable", not "printer offline".

ReturnsCopy Anchor Link

Promise<PrinterStatus>

write()Copy Anchor Link
