XPRINT GET PPI statement

Purpose

Retrieve the resolution of the host printer page.

Syntax

XPRINT GET PPI TO x&, y&

Remarks

XPRINT GET PPI retrieves the resolution (points per inch) of the host printer page.  The resolution is always specified in pixels, regardless of any XPRINT SCALE option.  If executed without a host printer attached, error 57 is generated, and the values 0,0 are returned.  This statement is particularly useful in drawing items such as rulers and graphs to a particular physical size.  There are 25.4 millimeters per inch, so just divide by 25.4 to convert from pixels per inch to pixels per millimeter.
