Hi,
My guess is that your RV will have a modified sign wave inverter, and any ink jet printer will work fine, including what you showed. However a laser printer should only be run from a generator, shore power or pure sign wave inverter.
When the RV is parked in a really warm area, the ink might dry out. Make sure that you take time to print something in color every 2-4 weeks. It can be difficult while full timing, but if you do not keep using it every once in a while, the ink in the print head can start to dry out, and might require cleaning or purging to make it print right again.
Another thought. There is no Office Depot or Costco near the National Parks. If you have a habit of printing photos, they will use a LOT of ink, and require frequent changes of ink cartridges. So you might want to pick up 2 refills of each color before hitting the road.
Fred.
