Printing from a Mac 45
Using the Cost Estimator
The Cost Estimator is found under the Cost tab in the Color Label
900 Utility.
Ink cost is automatically and continuously calculated based on the
black and color cartridge costs entered. Only the last printed label
cost is displayed. For reference, the print file name and number of
labels in the run is displayed at the top of the window. Adjust the
cartridge costs according to the actual price paid for them. The
estimate does not take currency into account so you can assume that
whatever value you entered is displayed in your currency.
Important Note: The cost per label represents the average cost label over an
entire run of labels. This means that the per label cost will decrease and
become more accurate as the number of labels printed increases. This is
because the ink that is used for beginning and periodic cartridge
maintenance is divided into a larger number of labels.
