Application No. 09/157,895
a printer device. Claim 1, directed toward the computer system,
is illustrative:
1. A computer system for outputting data to an output
device, comprising:
an application program for invoking a plurality of graphics
device interface functions to control the sending of data to the
output device;
a graphics device interface for invoking a plurality of
device driver functions for controlling the outputting of data in
response to the invocation of the plurality of graphics device
interface functions;
a text based minidriver containing a text based
characterization of the output device, the text based
characterization containing an implementation of device specific
device driver functions invoked by the graphic device interface,
the text based minidriver including means for outputting the text
based characterization; and
a modular universal driver which incorporates the text based
characterization passed by the text based minidriver, the modular
universal driver implementing the device specific driver
functions to control the outputting of data to the output device
in accordance with the incorporated text based characterization.
