Being able to print edge-to-edge is not necessary, and is mostly to do with practical feeding limitations. Alignment on the sheet is also allowed to suffer. But

Being able to print edge-to-edge is not necessary, and is mostly to do with practical feeding limitations. Alignment on the sheet is also allowed to suffer. But of what it does print, I’ve printed and observed printed a number of precise things on several different printers (mostly lasers, but at least one inkjet and a phaser, way back) with no visible warping. ¯\_(ツ)_/¯
