Is it possible to change the font of a template globally

We have a new plotter/ copier a KIP 7100, which has been working great, except that any text that is 1/16" high in our drawing template comes out to fine to read.  If we manually change it to a bold font, it becomes very readable.  The problem is we have thousands of drawings; is there a way to modify the template of an existing drawing other than opening them one at a time and changing the small text to Bold?
