BACKFEED - Backfeed Label
Plain English
Feeds the media backward by `n` dots (TSPL2 PG §BACKFEED p22–23). Range 1–9999. Used to retract the label after printing so the tear-off or cutter position is correct. TSPL printers use the alias `BACKUP n` for the same semantic (BACKFEED is the TSPL2 spelling; BACKUP is the older TSPL one). Conversion: at 200 DPI, 1 mm = 8 dots; at 300 DPI, 1 mm = 12 dots. ⚠️ Inappropriate values can cause paper jam or media wrinkle.
When to use
With tear-off or cutter modes when the label needs to retract to the correct tear/cut position after each print.
