# fmtdef

> [HTML Version](fmtdef.htm)

_Updated March 2026; see History_

You may specify the target printer, using standard Windows printer name syntax, by adding the following clause to the fmtdef parameter:

Printer=name

where name is the descriptive name of the printer, as it appears in the print manager control panel applet. If there are other clauses in the _fmtdef_ parameter, terminate this one with a "~" or ",". If no printer is specified, the current default printer is used.

The following directives can be added to the _fmtdef_ parameter to affect the preview settings:

PVzoom=###        zoom %, 0-200%, 0=fitted to window; default 0

PVpages=#         # pages in preview display; 1 or 2; default 1

PVtoolbar=<bool>  1/0,T/F for preview toolbar; default=1



If more than one clause is present in the _fmtdef_ parameter, separate them with the tilde character.
