From what I’ve seen photocopiers tend to be unreliable. At least if you rent one it should be covered if repairs are necessary.
I’m not sure whom we rent ours from, but if there is a problem someone is there to fix it quite quickly.
If you do get a laser printer or photcopier, make sure that the toner cartridges are widely available (i.e. you can walk into a Tsann Kuen 3C and pick one up in stock). I have a Samsung laser printer that’s several years old now and has been pretty good, but it’s a complete pain in the @$$ to get toner for it. Lately I’ve only been able to get the clone or refilled cartridges, not the real ones.
