set default printer (with one click)

hello,
two questions / requests:

1.on TLB site there is a pic where's a printer menu is shown:
   

where can I activate this menu?

(I pressupose there can the default printer be changed with one click?)

2.If not .. I'm sure I'm not the first with the idea to integrate a plugin or setting
where the default printer can be changed with one click!?

(exists there already such a plugin or setting? if not, whats the reason to waive
such a useful option? )

where can I activate this menu?

Right-click toolbar or menu where you want to create submenu with printers and select New->Menu. Then click "Predefined" button and select "Printers". Then click Next and Finish.

2.If not .. I'm sure I'm not the first with the idea to integrate a plugin or setting
where the default printer can be changed with one click!?

Hmm... It is possible to set printer as default with one click using "Related links" and interactive tips. This article shows command line parameters for printer.
This video shows how to setup related links and interactive tips. I've attached related links for my printer. Just replace "Xerox Phaser 3010" with your printer name and import related links for every printer.
