That sounds like the expected behavior to me. For example, if you examine the printer security using the Printer Management console, you may notice that there is a single ACE entry for a given security principal, with checkboxes for Print, Manage this Printer, and Management Documents.
However, if you click the Advanced security page, there may be two ACE's for that security principal, one for Manage this Printer and a second for Manage Documents, and there is usually an ACE for Everyone for the Print permission.
If you are interested in how the operating system defines and interprets these permissions, here is one possible view. As you can see, Manage Printers includes several other permissions, so that may explain the output.
