Chrome Version (from "Settings > About Google Chrome"): 49.0.2623.73 dev
Device Type: (iPad 2, iPhone 4, etc): iPhone 6S
URLs (if applicable): ticket print link from movietickets.com


Behavior in Safari (if applicable):


Steps to reproduce:
(1) Tap print link (I've seen this on any web site with a print link, including ana.co.jp boarding passes)
(2) Tap Google Cloud Print
(3) Tap Save to Google Drive
(4) Tap Save

Expected result:
Saves a PDF to Drive

Actual result:
Save button turns into a spinner that spins forever.  Chrome is hung: back arrow to left of "Print options" has no effect.  If you go to home screen and wait a bit, when you reopen chrome, you'll get "Chrome didn't shut down correctly" and a restore button.
