[Koha] jsprint setup + Receipt printing on Linux clients

[Chad Roseburg]

Thanks for all your input!

I had this feature working on a test server running the dev channel of Koha
maybe a month ago. It stopped working so, in frustration, I copied the code
from the Wiki. My previous code contained the single quotes and worked as
expected, but lacked the "try/catch" for falling back to normal printing if
jsPrint was not present. My point is that, with or without the single
quotes representing the 2nd argument, it is not working. Not working in
3.10 stable nor the latest packages for Debian. I thought maybe jsprint's
security settings were to blame, or possibly I'd run into a bug ...but it
could easily be the station I'm testing with. It sounds like the javascript
[ /w empty single quotes ] is correct so I will move on to other
possibilities.

@Randall
For many cases it's overkill, but there are scenarios where this would be
very handy.

1. Allows staff to use a single browser. Only Koha related pages print
silent to the receipt printer. Less confusion for substitutes and
techphobic staff members.
2. Centralized printer settings. Name every receipt printer "receipt", or
whatever, and you're done.
3. If you have Linux staff stations --- Firefox/Chrome do not use "Last
Used Printer", so your method does not work at all!
So this method allows easy, effortless and centralized receipt printer
setups for Debian/Ubu staff stations. I have not tried portable Firefox, so
that may be a way to get around the "Last Used Printer" issue, not sure.

Thanks again for your input! Would appreciate some guidance from other
libraries using staff Linux clients as to receipt setup.
