After sending each individual document to the print release station / print queue, make sure you WAIT for two pop-up windows. There may be a lag of several seconds to a minute, depending on the length of your document. Wait for the two pop-windows to show up - they may be behind open tabs or windows on your desktop.
Click "Print" in the first pop-up window, and click "OK" in the second pop-up window. Clicking "OK" in the second pop-up window sends your document to the print release station / print queue located next to each printer.
