Thanks Philippe,
Further to your message I still carried out a testing on Solidink. The printing is not recognized as capture fields by Anoto Pens. It behaves just as you would write on a white paper and does not store anything for transfer.

Thus the result is: Failed: Capture will not work on Solid ink printers as of now.

With this, I guess I will have to continue with Laser where ever Digital Pens & Capture is in use.

Posting this as a closure for other users who may be considering this options.
