Print several pages on one sheet — 2-up, 4-up and more
N-up printing puts several document pages side by side on one larger sheet — 2-up is two per sheet, 4-up is four, and so on. It is used to save paper when printing handouts, to make a contact-sheet overview of a document, or to lay out booklets.
Pages fill each sheet left to right, top to bottom, scaled to fit their cell with the aspect ratio preserved so nothing is stretched or cropped. 2-up uses a landscape sheet with two columns; the larger layouts use a portrait grid.
No. Each source page is embedded as vector content and scaled down mathematically, so text and lines stay crisp even at 9-up or 16-up — there is no rasterization step.
Yes — A4 or Letter. The tool orients the sheet automatically for the layout you pick.
