Desks — click to print
Printers you acquired
One printer, or many?
You're in the WITHOUT Singleton world. Click Get printer a few times and watch a new machine appear each time — each with its own queue. Then flip the toggle to WITH Singleton and click again: every call returns the same printer.
▸A desk can only print to a printer it has acquired. In the Singleton world every desk shares one machine — so a job sent from Desk A shows up for Desk B too.
