Print to file issues

[Anonymous]

I am struggling to get a "print to a file" printer defined in CUPS on my Mac. What I would like is to have a printer that simply writes the print data stream to disk instead of an actual printer.

It seems that the CUPS file URI is the appropriate vehicle to accomplish this, but I must be missing something basic.

I've changed the cupsd.conf file to have FileDevice set to yes
and the URI is set to file:/xyzzy

I created the directory /xyzzy and set the protection to world read write

The jobs are queue and exit the print queue, but no files appear in the /xyzzy directory.

What am I missing?
