Stefan and others - Stefan, you make the comment about the need for a "genuine HP cartridge" for toner transfer.  Is this true of most all HP printers? I'm thinking of the P-1006 for instance.  Is there really that much difference in the first 500 pages, and the 1200th page? 

How long will a laser toner cartridge last once it's started, then taken from the printer for storage?

Is it worth while to have two cartridges - one older for normal printing, and one "new" for TT?

Thanks to you and all others for comments.
