This seems a great Idea, but I have a question, (as always, lol).
It seems that only one printer can be selected, so how do you cover things like a spark plug and a full car assembly, print out?
I am using a HP450C 24" paper roll printer, which will print A1, and A2, from this roll.
Something like the sparkplug, will only need an A4 sheet and is a bit of a waste on A2 Size.
Have I missed something??
