WPAS (Windows Printing Automatic Stretching)
WPAS=Y or WPAS=y indicates that the automatic stretching of report pages should be enabled.
Any other value indicates that automatic stretching is not enabled.
The default value is WPAS=N.
When enabled, automatic page stretching causes a watch to made for the longest page that was printed in a report. This page is then logically stretched so that the entire printed page is covered by it. All other pages in the report are proportionately stretched the same way.
Automatic stretching is only enabled for a report when WPAS=Y is specified and the printed report contains at least 2 pages.
