ERP / finance invoice & statement silent print

Typical scenarios
Wide / multi-page tables
CSS page breaks—order table, long table.
Month-end batch
batchPrint—see batchPrint API.
Integration steps
- Install client on finance PC
- Extract report HTML from ERP UI
- Set A4 pdfOptions + printerName
- Preview then silent print
- Use formatPrintError for failures
