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?

Not easy to specify exactly. We are handing it off to 2D
We aren't doing any up-front verification here, but I don't want to copy 2D behaviour into the docs, even if I could be sure about that .. I may just want to be more waffly about what happens.
Could be printed to the printer, could be a failed job, could be an exception of some kind if some nice piece of Java code recognises a problem up-front
