Have you ever been in the situation where you need to print a document for a meeting immediately, but all the printers on your network are busy? This literally happens to me a couple times a week because one of my co-workers likes to print volumes on top of volumes of things she finds online.
It took only a little web searching but, I've found the answer. If you find yourself in the same situation and you are using a Mac running OSX, you can pool these printers together so your document will automatically print to the first available printer. For steps, read more
Just go to the Printer Setup Utility (in the Applications folder, within the Utilities folder), Command-click on all the printers you want to pool together, then go under the Printers menu and choose Pool Printers. A dialog will open where you can name your pool (the default name is “Printer Pool”), and it shows a list of printers that are in that pool.
You can click-and-drag the printers into the order that you want, and then click Create, which adds a new printer in your Printer list called Printer Pool. Choose that as your printer, and then when you choose Print, Mac OS X will start looking for the first available printer.
