I've been having a problem with my application sometimes (but not always) printing the full page, but it appears VERY small in the lower-left corner of the page.
I was having trouble reproducing it, but finally received a sample document from one of my users that let me reproduce it. Still, sometimes it prints correctly filling the page, other times, it prints scaled down in the lower-left corner of the page. I am using NSPrintOperation from an NSDocument to handle the printing operations. When trying to debug this issue, I examined the transformation from my view's drawRect method using CGContextGetCTM. I discovered something interesting: - When the printout appears scaled down, the transformation structure is the same as it is when the print preview image is rendered. - When the printout appears full-sized, the transformation structure is the identity matrix (ie. scale = 100%) Since the scale of the CGContext is the same when rendering the print preview as it is when rendering the full-sized page, this explains why my printouts are appearing very small in my output. Values 'a' and 'd' in the CGAffineTransformation structure indicate the scaling factor and for the print preview, it makes sense that it is scaled down for the print preview. But somehow, the transformation is not being set back to 100% scaling for the actual printing. I've looked for unbalanced CGContextSaveGState/CGContextRestoreGState calls, but they are all balanced. I've spent too much time trying to debug this. If anyone can give any ideas why my printouts are appearing scaled down, I would appreciate any help.
