Perhaps you saw an error in the document after you had started to print it. Your choices of what to do vary depending on where in the printing process the document is. The faster you can decide to cancel a job, the easier it is to do. While formatting a document for the printer, Word shows an animated progress icon on the status bar - pages rolling out the top of a printer. The number is the page currently being formatted for the printer.
Long documents take quite a while to prepare.
Short documents fly by faster than the icon can be drawn on the screen. Once Word is finished with its part, the progress icon returns to the spelling and grammar status icon. It just means that Word has finished the formatting . You'll have to go elsewhere now to stop the print job. When you tell a program to print a document, the Windows printer icon appears in the Tray beside the clock.
