Compared to the HP OneLam 400 A3, the HP OneLam Combo A3 scores with an integrated cutter, which makes it even easier to cut your documents straight, curled or perforated. The preset corners and centimetre grid make it easy to cut your laminated documents to the desired size. Like the other laminators in the HP OneLam range, this handy backloader... is suitable for both hot and cold lamination. With a film thickness of 75/80 microns to 125 microns, you can protect your photos, timetables or important documents from business cards up to A3 size from dirt and moisture.
