Module printsrvc 

Structs

PrintService

Struct to manage the printing service, including printer handling and job processing.

Enums

PrintAction

Enum defining the various actions supported by the PrintService.

Constants

BUFFER_OPEN_DRAWER

Predefined buffer for opening cash drawers.

COMMAND_VIEWER_NAME

Name of the CommandViewer pseudo-printer. It’s not a real OS device — when clients print to it, the job is routed to the command-viewer module which renders it into the local diagnostics web UI instead of paper. Keep this as a single source of truth: new(), get_print_list(), the print-job router, and availability checks all compare against this.

PRINT_VERSION

Version of the PrintService module.
