Settings: Print History

Every job that runs on every printer is recorded as a row in the print history table. The history is kept forever by default — it backs the file library's "Last Printed" column, per-printer statistics, and filament usage tracking. This card is where you manually prune old rows when you want to.

Set the day count and click Delete. Every history row older than that age is removed. The card shows a count of how many rows match before you click, so you can see the impact.

Pruning deletes the print history entries only — it does NOT delete:

• The G-code files themselves (those live in the library).
• Photos / thumbnails attached to completed jobs.
• Per-printer aggregate statistics.

Pruned rows are gone forever; the only way to recover them is to restore from a backup taken before the prune.

Print history is small — typically a few hundred bytes per job. A node printing a job a day for a decade is still well under 1 MB of history. Most users never need to prune. The control exists for users who want to maintain a tight history window for privacy or compliance reasons.
