It is not possible… Printing has to occur, yet there's no need to print pages on a real printer—printing to a file is enough.

The test could remove the produced file, but I see no reason to do so. Firstly, jtreg removes any files from the `scratch` directory; secondly, you can use the files to visually verify the range of printed pages… which could be invaluable if the test fails.
