Jessie CUPS print class problem

[Gary Dale <garydale@torfree.net>]

I'm running Jessie/64 on a laptop and wanted to route print to one of 3 
printers, so I created a print class called "photo" to handle the job 
management. I use lpr to actually start the printing using the command:

   lpr -P photo $1    (where $1 is the name of the file to be printed - 
in this case a jpeg.)

The jobs show up in the print queue for photo but never print. However 
if I move them to a specific printer they do print properly.

Am I missing something here?
