Do we need to close the bis here and below as well?

the reader was not added to the try block, it will not be closed.

src/java.desktop/share/classes/sun/print/PSPrinterJob.java line 398:

It will be better to use the same pattern everywhere, since the types are used in other places it will be good to use it here as well.
