Crate zpl_toolchain_print_client 

ZPL Print Client — send ZPL to Zebra and ZPL-compatible printers.

Supports TCP (port 9100), USB, and serial/Bluetooth SPP transports. The core API is synchronous (std::net), with no async runtime required.

Structs

BatchOptions

Options for batch printing operations.

BatchProgress

Progress report for batch printing.

BatchResult

Result of a batch print operation.

HostStatus

Parsed ~HS (Host Status) response.

JobId

Opaque identifier for a logical print job (single label or batch).

PrinterConfig

Complete printer configuration: timeouts + retry settings.

PrinterInfo

Parsed ~HI (Host Identification) response.

PrinterTimeouts

Timeout settings for printer connections.

ReconnectRetryPrinter

A retry wrapper that reconnects between attempts.

RetryConfig

Retry settings for transient failures.

RetryPrinter

A wrapper that adds retry-with-backoff to any Printer implementation.

TcpPrinter

A synchronous TCP connection to a ZPL printer.

Enums

JobPhase

Lifecycle phase of a print job.

PrintError

Printer error conditions, categorized by type.

PrintMode

Zebra print mode, as reported in ~HS line 2 field 4.

PrinterErrorKind

Specific printer error conditions derived from ~HS status flags.

Traits

Printer

Send data to a printer. All transports implement this.

Reconnectable

A printer that can re-establish its connection after a failure.

StatusQuery

Query printer status. Only bidirectional transports implement this.

Functions

create_job_id

Generate a new unique job ID.

expected_frame_count

Determine the expected number of STX/ETX frames for a given command.

read_frames

Read exactly expected_count STX/ETX framed responses from a stream.

resolve_printer_addr

Resolve a user-provided printer address string to a SocketAddr.

send_batch

Send a batch of labels with optional progress reporting.

send_batch_with_status

Send a batch of labels with status polling (requires bidirectional transport).

wait_for_completion

Poll ~HS until the printer reports no formats in buffer and no labels remaining, or until the timeout elapses.
