This program when run under Windows98 and printing to a
printer on an NT server (LaserJet 4L 300DPI) gives the following
output:

0.0,0.0
Graphics2D Xform = AffineTransform[[1.0, 0.0, 0.0], [0.0, 1.0, 0.0]]
Device Defualt Xform = AffineTransform[[1.0, 0.0, 0.0], [0.0, 1.0, 0.0]]
Device Normal Xform = AffineTransform[[1.0, 0.0, 0.0], [0.0, 1.0, 0.0]]
IMAGE_BUFFER
Graphics2D Xform = AffineTransform[[4.166666666666667, 0.0, 0.0], [0.0, 4.166666666666667, 0.0]]
Device Defualt Xform = AffineTransform[[1.0, 0.0, 0.0], [0.0, 1.0, 0.0]]
Device Normal Xform = AffineTransform[[1.0, 0.0, 0.0], [0.0, 1.0, 0.0]]
IMAGE_BUFFER

This shows (at least for the second call to Printable.print()) that the Graphics2D was rendering to a 300 DPI device. Calculated by multiplying 72 by the constants in the AffineTransform. This is what one would expect.

However Graphics2D.getDeviceConfiguration() returns a GraphicsConfiguration object that seems to be unrelated to the printer (it claims to be an IMAGE_BUFFER with an identity transform).

My understanding is that Graphics2D.getDeviceConfiguration() should return useful information rather that the incorrect information that it currently returns.

Don't try to run this under jdk 1.2.2 because you will get a NullPointerException.
