The Print Logger PE software is intended for a print management
(print control and audit printing activity) for printers at workstation,
based on Windows NT operation systems family. At this time this family
includes Windows 2000/XP and Windows Vista. The program inspects the print
jobs on a computer, where software is installed.
Main assignment of the program - collection of the information about sizes
(in pages and kilobytes) of local print jobs and record it to the database
for the subsequent analysis or creation reports about printing activity.

Note: if your printer has its own network interface or connected to the hardware
network print server( JetDirect or any other), you should install the printer as
a local printer on the server where Print Logger is installed. You should specify
the MS Standard TCP\IP port with the printer IP address as the port of the printer,
or the JetDirect(or other) port for a network print-sever. Users should connect to
printer using the print server as to the regular network printer:
\\YourServerName\YourPrinterName.

The program can also inspect sizes of print jobs based on defined quotas and prohibit
printing, if the quotas are exceeded (cost recovery and audit print). Quotas for
printing is very powerful and effective mechanism for cost management on printing
in your organization. Limiting printing activities for some employees, you can really
save on a paper, a toner for printers (especial at a color printing), expenses for
repair and service for printers.
