qz.findPrinter() not working #96

Closed tresf closed 9 years ago

tresf commented 9 years ago

In 1.8 (applet), qz.findPrinter() was a completely valid command. Now with 1.9, it is not.

The exact error message is:

Sep 1, 2015 12:00:00 AM qz.PrintApplet run

Partially caused with the introduction of #86, as dummy printer logic was doing string comparison against null causing NPE. Closed via bbf0263, checks for null prior to comparing string.
