The default character-cell size is a device-dependent value. You do not need to know this value unless you want to switch back to the initial default value after having specified another value. It is recommended that you save initial default values using GpiSavePS.

The default character cell, like other default attributes, can be set using GpiSetDefAttrs(CBB_BOX). If necessary, you can query the current default value using GpiQueryDefAttrs.
