PRODUCTIVITY
Evaluating print productivity is not as simple as timing copy jobs. The printing process involves several steps and can be
affected by a variety of factors along the way.
The document must first be spooled by the printer driver into a PCL or PostScript file. The PCL or PostScript file is then sent to
the printer where it is raster image processed (RIPped) into image data by the device processor. The image data is then sent to
the marking engine and output as printed pages.
There are three obvious factors highlighted above (spool time, RIP time, and print engine speed), which can all make or break a
device’s overall productivity. Add into the equation other factors, such as concurrency and contention, and one would have a
real world situation.
However, it is possible to time and compare these factors through the use of careful preparation, conditioning and testing.
Following are charts that show printing performance when tested under controlled conditions:
