If you are trying to print from the library's 3rd floor computer lab, select the printer "sl-3rd-floor-black" OR "sl-3rd-floor-color," depending on whether you wish to print in black and white (10¢/page) or in color (50¢/page) ink.
Please follow the same guidelines for 2nd floor printing: "sl-2nd-floor-black" & "sl-2nd-floor-color," and the same for 4th floor printing: "sl-4th-floor-black" & "sl-4th-floor-color."
