List All Printers: Exception in thread "Thread-12" java.util.regex.PatternSyntaxException: Illegal repetition near index 1 #38

What steps will reproduce the problem?
1. Open sample.html
2. Click List All Printers (nothing happens)
3. Look at the Java Console

What version of the product are you using? On what operating system?
Latest version. Through Apache in Firefox on Windows 7

The "Print" button works OK. I have created a printer called "zebra" to test.

Full Java Console output:

I'm evaluating jZebra to see if it can be used in a web-based point of sale 
system.

Good find.  Take the brackets off and it should work. I'll fix this in next 
release.

Applied fix to sample.html (put escape character in front of brackets)

applet.findPrinter("\\{dummy printer name for listing\\}");

Updated in version 1.2.1.  Download here:
