Page per minute
Abbreviated as ppm. This specification is always exaggerated. Laser printers generally print text pages only slightly slower than the manufacturers' claims. But the claims for inkjets are typically done at low-quality settings while using very simple text pages--in other words, a speed you'll never see in real life. Reality check: Printing a single A4-sized color photo on an inkjet may take anywhere from 2 to 30 minutes.
