title: Google cloud print - print multiple copies
body: <p>I have a problem with google cloud print api. I can't find an example for adding capabilities to a a printer (specifically multiple copies to a printer LaserJet Pro P1102w). 
  I used <a href="https://developers.google.com/cloud-print/docs/proxyinterfaces#register" rel="nofollow">https://developers.google.com/cloud-print/docs/proxyinterfaces#register</a> this as reference, but it didn't help me much. It only describes what response should be like, and i can't get anything similar to that.
  If I use "list" on my google account - printers, I don't get any capabilities listed as part of my printers.
  If anyone has any idea what to do, please let me know.</p>
