/**
 * Tests for getPrinterImage — model → printer card image resolver.
 *
 * X2D support (#988): both the display name "X2D" and the internal SSDP
 * code "N6" must resolve to /img/printers/x2d.png so the Printers page
 * and PrinterInfoModal show the correct artwork instead of falling back
 * to default.png.
