Can you also change the reference to kChromeUIPrintHost to be behind
ENABLE_PRINTING in chrome/browser/ui/webui/chrome_web_ui_controller_factory.cc?

I think if you do that, then you can put kChromeUIPrintHost behind
ENABLE_PRINTING as well.

Done. 
Normally we don't disable the declarations when upstreaming Android specific
code that disables some features to reduce the number of ifdefs.
