Hi All,
Please review a fix for an issue where it was found that setting left
margin of 2" is ignored and when we query
PrinterJob.job.getPageFormat(PrintRequestAttributeSet)
we get the default paper mediapritable area of x=1" instead of the set 2".
Bug: https://bugs.openjdk.java.net/browse/JDK-6789262
webrev: http://cr.openjdk.java.net/~psadhukhan/6789262/webrev.00/
This is because
it was found that getPageFormat() calls
Win32PrintService#isAttributeValueSupported() where we call
isSupportedMediaPrintableArea()
to check if the mediaprintable area is matching with the media size that
has been cached. It gets the paperID by calling findPaperID() and stores
the mpa of that paper in MediaPrintableArea[]
I see that my printer supports 43 mediasize names (like iso_a4, iso_a5,
na_letter etc) and none of the 43 mediaPrintables equals the mpa value
of (50.4, 25.4, 133.8, 246.2)mm
---------------isSupportedMediaPrintableArea()---------
if (mediaPrintables != null) {
for (int i=0; i<mediaPrintables.length; i++) {
if (mpa.equals(mediaPrintables[i])) {
return true;
}
}
}
----------------------
So, it seems this check isSupportedMediaPrintableArea() is preventing
valid mpa values to be propagated to RasterPrinterJob to be used for
printing.
I see in linux and mac, *IPPPrintService*#isAttributeValueSupported() is
called which does not have this isSupportedMediaPrintableArea() check
and there this left margin of 2" is not ignored and stored properly.
So, the proposed fix do away with this isSupportedMediaPrintableArea()
call from Win32PrintService#isAttributeValueSupported.
