Factors Affecting Printer Performance
Several factors affect the time it takes to print a job. Among these is
printer speed, measured in pages per minute (ppm). Factors that
affect printer speed include special media (such as transparencies,
glossy media, and heavy media) and custom-size media.
The time required to download a print job from the computer to the
printer also affects print speed. Among the factors that affect
download time are:
● complex or large graphics
● color versus black and white
● the printer’s I/O configuration (network versus parallel speed)
● 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 Emulation)
Note Adding additional printer memory may resolve memory problems,
improve how the printer handles complex graphics, and improve
download times, but will not increase printer speed.
