missing reportData argument in constructor

Error message

missing reportData argument in constructor

What it means

Defensive constructor check in NewPrinter: the reportData parameter (*report.Data) was nil. It indicates a wiring bug in the caller — the collected report data was never created or passed — not a user configuration problem.

Solutions

1. Ensure the caller creates a *report.Data and passes it to NewPrinter
2. Review run-command wiring that assembles printers and report data
