Using printers with Mac OS X is generally very easy. In many cases the operating system does not even require printer drivers to be installed, and it usually does a good job of monitoring a printer's supply levels such as ink and paper. From time to time, however, the operating system may have incorrect information about supplies that can prevent you from printing correctly. In these situations you will often need to reset the printing system in order for the software to recognise supply levels correctly.
Click the "System Preferences" icon located in the dock. This icon looks like three grey gears.
Click "Print & Fax" located in the "Hardware" section of the window, then choose your printer in the window that pops up. The available printers are listed along the left side of the window.
Control-click the printer you wish to reset and choose "Reset Printing System." A dialogue box will ask if you are sure you wish to reset the printing system. Click "Yes."
If the above steps do not resolve the issue, check your printer manufacturer's website for updated driver software. In some cases, software updates can fix the problem.
