I have Epson ES-300WR scanner, which works fast, is portable, and functions wired or wirelessly. I now have 3 printers: Two dual tray Brother HL-L6200DWTs and an HP triple tray laser Jet M452DN. Having At least one backup printer is VERY useful when you consider that the high-volume demands of printing for NSA work puts an enormous burden on these printers. With only one printer, when defects arise your work will stop while you are attemptIng to diagnose and repair your printer malfunction. A spare printer of the same make and model lets you buy the same expendable materials such as toner cartridges And drums so that your supply stock is interchangeable. Another significant benefit of having two printers is that the low-cost printers are not built for what is called ’continuous duty cycle’, or constant use. When you are printing 100+ page documents, these printers get very warm and it is important to provide a cool down in between printing jobs to prevent print quality degradation and damage that will result to the printers.
For medium to high volume continuous duty printing, expensive work group class printers would normally be preferred, but these end up costing in excess of $1300 at purchase and their Materials maintenance costs are much higher. I chose the Brother printers because they are extremely inexpensive monochrome printers and if managed well, seem to provide very reliable performance and low-cost maintainability. If one gets to a point of having a critical malfunction, then the replacement cost is so low that it is very affordable and you just move forward.
