Doublesided Print Alignment
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. Purpose is so that I do not have to print singlesided, paste the wheels together & then laminate. The project calls for printing all 4 wheels (2 ea from each inkscape drawing) back-to-back so that only two wheels are necessary for laminating.
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.
Drawing 1:
wheel 1 x 120 y 560 px
wheel 2 x 250 y 150 px
Drawing 2:
wheel 1 x 240 y 570 px
wheel 2 x 140 y 130
Note the above are just samples and are not the closest alignment(s) when printed. That is just what I have on the currently opened drawings at this time.
I can of course move each drawings wheels individually to position. But in order to test I need to print each on each side in color. So, I wonder if there is some magical x/y number/method I can use instead of trial & error (mostly error). Printed paper is US Letter (8.5x11").

Any suggestions?
Hi!
Some short comments, not necessarily helpful:

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.)

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...)

I would save the items as e.g., eps files and import them to Scribus or use them in pdftex. Exact placement should be possible in either tool.

IMHO the exact placement is not the problem, that can be done in Inkscape too.
Most consumer grade printers do not print exaclty centered on the page so one has to correct those deficiencies of the printer with other means than correct placement.

Well... good news/bad news. Finally got everything lined up using regular paper, so I then loaded 61 pound double-sided photo matte paper only to find that I had to realign all over again. Apparently the printer (Canon MP750) adjusts the alignment for the heavier paper. So now I have saved templates for that paper & printer.
With regard to aligning; I did a copy & paste in place from the wheels from drawing 1 onto drawing 2. That way I could adjust to wheels in drawing 2 close to the Y position in drawing 1. The rest was just printing test runs and then adjusting X/Y in 5px increments. Painfully slow & expensive (paper & ink). Next test will be to export to PDF, join the pages & print the PDF version w/same paper, but use the regular duplex feed instead of the back sheet feeder.
As an FYI, here are the coordinates that I got to work on the 61lb paper:
Drawing 1:
wheel 1 x 120 y 560 px
wheel 2 x 250 y 150 px
Drawing 2:
wheel 1 x 250 y 565 px
wheel 2 x 120 y 155
