Why is Lisa unable to increase the priority of her print job?

Lisa is unable to increase the priority of her print job because managing documents, including changing the priority of print jobs, typically requires specific permissions on the printer. The permission to manage documents allows a user to modify or control print jobs, including changing their order or priority. Without this permission, any attempt to alter the print job settings will be restricted, preventing her from increasing the priority of her own print job.

Other choices pertain to different aspects of printing permissions and settings. For example, enabling Branch Office Direct Printing affects how print jobs are routed but doesn't specifically relate to job priority changes. Similarly, not having Print permission would prevent her from sending a print job to the printer at all, rather than adjusting its priority. Lastly, the installation of the Internet Printing component falls under enhancing printing capabilities but does not directly impact her ability to manage job priorities if she already has access to the shared printer.
