I cannot seem to print iCloud notes directly from a FireFox browser session (multiple versions), though I have been able to from a Safari session (mutiple versions).
I have a MBPro running 10.7.3 (no icloud app); if I log into the "web" version of icloud (FFox 15.0.1) and try to print an icloud note (File -> Print) from the browser window, all that comes up (print, or "open PDF in Preview") is a blacked page, no note. If I open Safari (5.1.5) AND make sure the cursor is active in the actual note frame, then File -> Print actually works.
Another way I can print from iCloud Notes is on another machine in the house running 10.8.1 and the native icloud app, there File-> Print works. Also on this machine, if I open browser (FFox 16.0.1), log into icloud, print from web-based icloud, same problem, prints a black page. If I open another browser (Safari 6.0), AND make sure the cursor is active in the actual note window, then File-> Print actually works.
On an ipad, I don't have print options, as I don't have an airprint-enabled printer (running ios% if that matters, have no desire to upgrade to ios6 yet).
Curses.
[As far as why so many versions of things on different machines, I spend a lot of time in a rural area with 2MBit/s download speeds, which makes major upgrades difficult on multiple platforms.]
