Who's logged onto which computer? Which resources are they requesting? Of course, we know there are all sorts of logging and auditing tools lying around.

Here we discuss on some of the best print managers

It permits a workstation to act as a print server. The workstation job acts like a host that can recognize related jobs from patron computers, course them, and drive them to selected printer (to a selected printer/ to the selected printer/s).
