Hi,

XAR is a vector based format of the Xara graphics software, so you wouldn't be able to just convert it to a pixel-based format like JPEG. The software itself would have to render it to a pixel format. Unfortunately, this feature is not included in the Xtreme Print Studio, which is essentially just a cut down version of the Xara graphics software. However, here's an idea, which is also a technically better and more elegant solution than taking a pixel-based file to the printer: Use one of those PDF converters that act as a printer driver emulation and "print" the file from Xtreme Print Studio to a PDF file. Then take the PDF file to Kinkos. That should do the trick. There are enough free solution for such a PDF converter. I just ran a search on Google and this one came up:

Don't remember which one I used a few years ago, but after installation this will come up as an option for your printer driver. Just pick that in the printer setup and create your PDF.

Alternatively, I guess you could get a trial version of Xara Xtreme from the Xara website to export the XAR project as JPEG. Should be possible in the trial.

I hope this helps.
