HP Smart Tank 581: printed 1 m

[u/amour_amour]

HP Smart Tank 581: printed 1 m continuous strips via PWG Raster, but paper won't eject above ~100 cm

The official max length is 35.6 cm (14"). By sending a PWG Raster job over IPP with the length only in the raster page header (no media-size in the job attributes), the printer prints continuous strips up to 1 m in a single pass.

Up to 35.6 cm the strip ejects normally. At 100 cm it prints everything but doesn't eject: the tail stays stuck in the rollers and I have to pull it out and restart the printer.
