Struct PrinterStatus 

pub struct PrinterStatus {
    pub online: bool,
    pub cover_open: bool,
    pub paper_end: bool,
    pub paper_near_end: bool,
    pub drawer_pin3_high: bool,
}

The printer’s condition after a print, as both dialects report it.

Read it back from the printer’s own DLE EOT replies with PrinterStatus::from_dle_eot, so faults and the drawer setting count exactly as they do for Web Serial.

use hardless_http_dialects::PrinterStatus;
// DLE EOT 1, 2 and 4 replies of a printer that is out of paper.
let status = PrinterStatus::from_dle_eot(0x1A, 0x32, 0x7E);
assert!(status.paper_end && status.paper_near_end && !status.online);

Fields

online: bool

The printer is online (not stopped by paper end or an open cover).

cover_open: bool

The cover is open.

paper_end: bool

The roll is empty.

paper_near_end: bool

The roll is nearly empty.

drawer_pin3_high: bool

The drawer-kick connector’s pin 3 (the drawer sensor) reads high.
