3.5 Updating the Minidriver Resolution and Measurement Data

A number of the data structures in a minidriver's data table contain
measurement values (that is, graphics resolutions, paper sizes,
unprintable-region dimensions, line-feed values, and so on). Each of the
values is specified in master units. The Update References? control
indicates whether or not UniTool should update each measurement in each
data structure. If this control is checked and you choose the OK button,
UniTool will update all measurements; otherwise UniTool will leave the
original measurement values. If some of the measurements do not factor
evenly into the new master units and the Update References? box is checked,
UniTool will issue an error message which identifies the faulty value.
