Hi!
Some short comments, not necessarily helpful:

I have two inkscape drawings, each have two 360 degree protractor wheels on them; exact same size. I am attempting to print drawing 1, turn the paper (it's doublesided photo paper) and then print drawing 2, and get the prints to align properly. [...]
Most printers I know tend to pull in the paper slightly different for each single print. This usually leads to the print being slightly to the left or right or slightly turned (up/down motion is usually minimal and not notable). What helps with this is to align the side of the (adjustable?) paper tray so that it is really flush to the paper. This way the paper has the best chance of getting into the printer in the same way for each print. (I'm a non native speaker, don't know if that was clear.)
I have tried moving the wheels individually (on drawing 1 only so that drawing 2 is the base) by x & y pixels, but so far haven't found the proper combination to get them to align exactly with the backside of drawing 2. I'm running out of ink & paper with each attempt. [...]
What I would do (but since my printer is awfully imprecise I have never tried) is to print them with the current setting, stick a small slim needle through a distinct feature of the wheel you wan't to move. Then measure the offset between the needle and this distinct feature on the other side at least down to 1/10 of an inch (preferably to 1/10 of a millimeter). With this measurements set inkscape to inches or millimeters as measuring unit, move the wheel accordingly and print.
As I said, I never have tried this but it could work. (It removes a lot of the variables from the measuring process...)
