A watermark property is specified for a print queue, subject to control only by network administrators. The value within the watermark may be a pointer to a graphic image, text, or a logical value, allowing flexible specification of a water-mark on a printer by printer basis. The queue watermark property overrides any print job watermark properties before the print job is submitted to the print driver, regardless of whether the print job watermark was set in the job properties locally or remotely, by a user or an application. The queue watermark property thus serves as a distinct, mandatory watermark associated with the print queue, whether local or network. The watermark property setting is retained by a persistent parameter in configuration information for the print server hosting the print queue, which is employed to initialize the queue. As a queue property, which ordinary users will not normally be permitted to control, the watermark property may be protected from modification or circumvention by any user not having network administrator status.
