Printing Maps in Oasis montaj
Oasis montaj
, by default, uses your Windows system drivers to create printer or plotter
output. When you start printing maps for the first time, you will most likely accept the
defaults. Depending on your driver’s performance however, you may want to add a new
configuration that uses more advanced printing options.
Geosoft provides a special printer setup capability that starts an internal rasterizing engine
that performs most of the print/plot processing and passes it to the driver for final output.
