Refactor object retrieval and template data handling in DocumentPrinterClient

- Updated the object retrieval logic to support multiple document objects, enhancing flexibility in handling document jobs.
- Introduced a new `templateData` structure to consolidate retrieved objects, improving the deployment process in the `deploy` method.
- Enhanced error handling and data management during the document printing workflow, ensuring more robust operations.
