The HP LaserJet MFP M140we hits 21 ppm on A4, 20 on letter

20 pages per minute on letter, 21 on A4. The HP LaserJet MFP M140we is an entry-level mono laser multifunction, and its speed reflects that — adequate for a small office or personal use, not designed for a busy workgroup. The slight edge for A4 over letter is a small curiosity worth noting.
