The Brother MFC-L3770CDW Laser is a better printer for office use than the HP OfficeJet 7740 Pro. The Brother is a laser printer, so it can yield even more pages before its toner cartridges need to be replaced, and its print speed is much faster too, although its first black-only page takes a bit longer to get started. However, the HP is more versatile. It has a significantly better photo printing quality, it has a USB port so that you can print directly from your thumb drive, and its overall cost-per-print is slightly lower too. That being said, you’ll need to change its inkjet cartridges a bit more frequently though.
