- Added SNMP configuration options to `AppConfig` for querying printer status. - Extended `PrintInstruction` in the proto file to support additional fields for remote file URLs and raw data. - Implemented logic in `CupsClient` to retrieve printer paper levels and page counts via SNMP. - Updated `Cargo.toml` to include `snmp` and `reqwest` dependencies for network communication. - Refactored `TempPdf` handling to support multiple data sources for printing. - Improved error handling and logging for better diagnostics during print operations.
