Amazon has the Brother Multi-Function Wireless Monochrome Laser Printer for only $99.99 shipped. That’s half-off the list price and the lowest we could find it for.
It can print up to 27ppm and produce a professional-looking output. It has built-in wireless and Ethernet network interfaces for flexible connectivity and automatic duplex for producing two-sided output that helps reduce paper use. Also it has an adjustable 250-sheet capacity paper tray with a manual feed slot for printing envelopes and letterheads.
Amazon customers gave it 4.4/5 stars and left great reviews.
