Seeing where this thread is going, I would not recommend any laser printer for use in a RV (and I don't think that was the original question). Laser printers are not meant to be shaken, and their power needs are hard on the limited power availability typical of RVs. For RV use, an inkjet that packages new print heads with each ink supply, and if you don't use the printer regularly, expect to replace cartridges often. My experience here is mostly Canon and HP. I liked the office grade HP printers in the Deskjet 930 series (they shared cartridge tech with the 36-inch plotters we used to print 200-500 fett of maps per day) but I can no longer find drivers and the cartridges are starting to get scarce and very expensive.
Here, we are trying to sort out the difference between "durable," the original question, and "rugged," the mobile printer issue. There are inkjet printers designed specifically for mobile use, they travel well but are relatively expensive to use and are slow compared to office grade inkjet printers.
