- When I print a PostScript file, why do I get one blank page for every page
- printed?
-
- Your PostScript file probably contains calls to the PostScript 'showpage'
- operator. This operator is also called by the LaserWriter driver when it
- receives the PrClosePage call. The solution to this problem is to strip
- 'showpage' calls from the file before sending it to the LaserWriter. If
- you send one Quickdraw graphic at the beginning of each page,
-
- (ie. MoveTo(-32000, -32000); Line(0, 0);)
-
- the LaserWriter driver will handle calling showpage for you. Versions of
- the LaserWriter driver before 5.2 do not send the 'showpage' operator
- unless a Quickdraw drawing routine (ie. something other than PicComment) is
- sent. This is why you need to do the MoveTo/LineTo. Versions 5.2 and
- later will send the 'showpage' operator whether any Quickdraw has been sent
- or not. Since you can't be sure whether showpage will be sent for you or
- not, the best solution is to always let the LaserWriter driver send it.
