Controls the method of printing the slips that Sentral generates. 

– HTML (manual printing) printing prints a web page directly using your browser. 

For help with setting this up correctly, you may refer to this article in the Help Centre. 

– Java Applet (requires Java in browser) printing uses an inline application which runs in your browser. 

Most major internet browsers are moving away from allowing Java applets to be run 

in browsers, which affects the ability for this method of automatic slip printing to work.
