Let’s take it step by step.
First, here’s a version with the dependence on Keyboard Maestro (for options settings) disabled.
What happens if you run this (making sure to copy all of the code - accidentally missing out a line or two at the end or start is another common glitch that can easily arise):
// COPY THE ACTIVE TASKPAPER DOCUMENT INTO THE CLIPBOARD IN A FORM THAT CAN BE
// PREVIEWED AND PRINTED (WITH CSS STYLESHEETS) USING MARKED 2
// appIsInstalled :: String -> Bool
function appIsInstalled(strBundleId) {
ObjC.import('AppKit');

// Marked 2 > Preview > Clipboard Preview
// http://marked2app.com/
// If Marked 2 is installed, the script opens it and displays a CSS-formatted clipboard preview
// Draft 0.09 Rob Trew 2016-04-13
// 0.09 Allows for hiding of @saved searches
// 0.08 Allows for printing only outline-visible + filter-visible lines
// 0.06 Allows for an API change in 3.2 Preview (197)
// (item.bodyContentString || item.bodyDisplayString)
// 0.05 adds further options (at bottom of script):
// - baseHeaderLevel
// - hideProjectColon
// - markedStyle
// - tagEmphasis
// - tagsToHide
// 0.02 adds option for blank line between a task and its note(s)
