The ANSI character set which is supported by Windows includes 256
characters, numbered 0 to 255. The standard definition of characters 0 to 127
correspond to the letters, numbers and symbols seen on a standard U.S.
keyboard and it is these characters that are predominantly used in the English
language.

The remaining  characters (128 to 255) are generally unused and correspond to
characters not usually found on your computer’s keyboard, such as accented
letters, currency symbols and mathematical symbols.

PARIS provides you with the option to control the number of characters
downloaded in a character set by allowing you to modify the character selection
table.

Why control the number of characters?

PARIS manages printer resources, the downloading of fonts, forms and
graphics to the printer, according to the capabilities of the device and PDL
(Page Description Language) being used. By controlling the number of
characters in a character set, the transmission time to the printer to download
fonts can be reduced.

For example, if you are using a printer that requires the resources to be sent
every time a job is printed, the transmission time to the printer is increased. If
you are printing multiple jobs, you can reduce the transmission time by
speeding up the downloading of fonts. This is achieved by modifying the
number of characters being downloaded.
