NSPrintOperation (-_printPaginateWithInfo:knowsRange:)

[Georg Fleischmann]

Another small issue in NSPrintOperation (that I just worked around in  
my code).
If NSPrintScalingFactor is not set, printing will fail in  
[NSPrintOperation -_printPaginateWithInfo:knowsRange:]:

  info->printScale = [[dict objectForKey: NSPrintScalingFactor]  
doubleValue];

In this line, the Dictionary will return nil and the doubleValue ends  
up undefined or 0. It should be 1.0.
I suggest something like:

if ([dict objectForKey: NSPrintScalingFactor])
  info->printScale = [[dict objectForKey: NSPrintScalingFactor]  
doubleValue];
else
  info->printScale = 1.0;


Best wishes,
