RFR: 8373239: Test java/awt/print/PrinterJob/PageRanges.java fails with incorrect selection of printed pages

[Prasanta Sadhukhan]

If same `PrinterJob `is reused to first print user-set `PageRange `pages and then print ALL pages, it prints the first print job correctly as the page range is set but 2nd job doesn't print ALL pages and reprint the same page range as `from` and `to` page are not reset and reused

Fix is made to check if page range is not set then print all pages
