print zpl in your downloads folder to a ups zp450
add paths to the .desktop file, then move that file to an appropriate location so you can access it easily.
Intended operation is to use your app launcher hotkey (typically super) and type in zprint, pinning to a dock would work as well. This will print and append .used to the file name any .zpl file in your downloads folder. Modification will need to be done to run it with printers other than zebra zp450.
