And I wouldn't want to single out a security exception (what about a read-only file system?). I think that whatever the reason, if the file can't be written to, we should treat it consistently. Probably by ignoring the request. I presume that's what will happen if the print driver doesn't support print-to-file?

So the SE will occur only if there is a SM and the code in J2DPrinterJob.checkPermission() rejects it.
