- Selphy CP820/CP910/CP1000/CP1200:
-
-  Radically different spool file format!  300dpi, same print sizes, but also
-  adding a 50x50mm sticker and 22x17.3mm ministickers, though I think the
-  driver treats all of those as 'C' sizes for printing purposes.
-
-  Printer does *not* require use of a spooler!  Huzzah!

-  It is worth mentioning that the image payload is Y'CbCr rather than the
-  traditional YMC (or even BGR) of other dyseubs.  Our best guess is that
-  we need to use the JPEG coefficients, although we realistically have
-  no way of confirming this.
-
-  It is hoped that the printers do support YMC data, but as of yet we
-  have no way of determining if this is possible.
-
-  Also, we have reports of the printer not quite behaving properly
-  in the face of multiple jobs; it's possible this thing may need a
-  backend after all, but more sniffs will need to be performed to determine
-  what the status readbacks (if any) mean.
