Abbr. on a paper tray

LTR

Not available

This clue is asking for a common abbreviation you’d see on a paper tray, like the ones in an office printer. "LTR" stands for "letter," the standard paper size in the U.S. and Canada, often labeled on trays to distinguish it from legal or A4 sizes. The abbreviation is straightforward—no wordplay or tricks—just a shorthand term for a familiar office supply.
