Summary: While looking for an economical monochrome laser printer to plug into our home network of four Macs, I stumbled across the e120n on sale for $99. Mac-ready, network-ready, under $100, laser. Hmmm . . . thirty seconds later I was standing in line to pay for it.

Installation to a wireless network via an Airport Express station was as easy as attaching the USB cable. Installation of the proper drivers from the install package on the CD was a snap, and within minutes the printer was up and running. It's now our routine basic printer, and is doing a wonderful job.

Summary: I needed a new laser printer and after checking several reviews, I settled on the Lexmark E120n. The main selling point for me was that the printer was network ready with the built in ethernet adapter. This means that the printer can plug in to a router and anyone on the network can print to it without a 'host' printer having to be on or without having to buy a print server. This feature works perfectly and was simple to setup.
The printer prints nice clean text and is very fast, like most laser printers. The only downside that I have seen with this printer is that the printhead or something inside the printer makes a 'resetting' noise every couple of hours if the computer is left in standby mode, which I do. This resetting noise only lasts about 1 second, but with the printer in my bedroom, it can be annoying to hear in the middle of the night. It is not loud enough to make me up, though.
Otherwise, this is a great printer. It looks nice with its black and silver matte finish and it works perfectly. Highly recommended.

Summary: Can be used to print bankable checks using MICR toner cartridge from checksnet website. I also found the MICR cartridge allowed me to lower toner darkness setting when printing documents which makes this a very economical laser printer.
