Hints and Tips Color job processing efficiencies The time required to process a job can depend primarily on four variables: • Time for a client workstation to generate the Page Description Language (PDL, i.e. PostScript, HP-PCL, TIFF, etc.). • Time to transfer the job PDL across the net and be marked as received by the Xerox FreeFlow Print Server. • Time required to RIP the PDL to produce the bit maps that the print engine can use. • Time required to write the RIPped bit maps to the print engine and generate paper. Time used to generate the PDL This variable is strongly influenced by the speed of the client workstation, the print driver being used by the application, and the complexity of the pages to be printed. Time used to transfer PDL This variable is influenced by the speed of the network connection between the client workstation and the Xerox FreeFlow Print Server. It is also impacted by the number of workstations on the network, by the configuration of the network (that is, the number and speed of the gateways and routers and by the number of simultaneous network connections that the Xerox FreeFlow Print Server has to manage).

Hints and Tips
Color job processing efficiencies
The time required to process a job can depend primarily on four
variables:
•
Time for a client workstation to generate the Page Description
Language (PDL, i.e. PostScript, HP-PCL, TIFF, etc.).
•
Time to transfer the job PDL across the net and be marked as
received by the Xerox FreeFlow Print Server.
•
Time required to RIP the PDL to produce the bit maps that the
print engine can use.
•
Time required to write the RIPped bit maps to the print engine
and generate paper.
Time used to generate the PDL
This variable is strongly influenced by the speed of the client
workstation, the print driver being used by the application, and the
complexity of the pages to be printed.
Time used to transfer PDL
This variable is influenced by the speed of the network connection
between the client workstation and the Xerox FreeFlow Print
Server. It is also impacted by the number of workstations on the
network, by the configuration of the network (that is, the number
and speed of the gateways and routers and by the number of
simultaneous network connections that the Xerox FreeFlow Print
Server has to manage). Finally it is impacted by the complexity of
the pages being printed (i.e. the size of the PDL files being
transferred).
Time required to RIP PDL
This variable is influenced by the efficiency of the PDL to be
RIPed, the complexity of the pages being RIPped, the number and
resolution of images included, and the media/color space
transforms being performed on the data before imaging/printing.
Time required to print PDL
This variable is influenced by the media being used and the paper
path through the printer. Whether the printing is face up or down,
simplex or duplex, all one size or a mix of sizes to be drawn from
different trays all make a difference. In addition, the complexity of
the pages and therefore the number of Image Quality adjustments
that the print engine makes during a job also impact the final
performance of the printer as it generates paper.
