Factors affecting printer performance
Several factors affect the time it takes to print a job. Among these is maximum printer speed,
measured in pages per minute (ppm). Other factors that affect printing speed include the use
of special media (such as transparencies, glossy media, heavy media, and custom-size
media), printer processing time, and download time.
The time required to download a print job from the computer and to process the job depends
on the following variables:
● the complexity and size of graphics
● the printer’s I/O configuration (network versus parallel)
● the speed of the computer you are using
● the amount of printer memory installed
● the network operating system and configuration (if applicable)
● printer personality (PCL or PostScript 3 emulation)
Note Adding additional printer memory might resolve memory problems, improve how the printer
handles complex graphics, and improve download times, but it will not increase maximum
printer speed (ppm rating).
