Inkscape cannot directly create a vector job for the Zing laser, but there’s a workaround:

  1. Print from Inkscape to CutePDF (installed) Printer, which will create a PDF file.
  2. Open the PDF with Adobe Reader
  3. Print from Adobe to the laser as a regular print job.

I’ve tested this with Inkscape (works fine). It should also work with any other software which generates a vector-based PDF file.
