/*
* Canon SELPHY ES1 series print assister
*
* (c) 2007-2011 Solomon Peachy <pizza@shaftnet.org>
*
* The SELPHY ES-series printers from Canon requires intelligent buffering
* of the raw spool data in order to keep the printer from locking up.
*
* Known supported printers:
*
* SELPHY ES1, SELPHY ES2, SELPHY ES30
*
* Supported but untested:
*
* SELPHY ES20, SELPHY ES3
* SELPHY CP-760 and all other CP-series printers EXCEPT for CP-790
*
* NOT currently supported:
*
* SELPHY ES40, CP-790
* (They use different stream formats, and may have different readbacks;
* I will update this as needed and as I get hardware to test..)
*

* (c) 2007-2012 Solomon Peachy <pizza@shaftnet.org>
*
* The SELPHY ES-series printers from Canon requires intelligent buffering
* of the raw spool data in order to keep the printer from locking up.
*
* Known supported printers:
*
* SELPHY ES1, SELPHY ES2, SELPHY ES30
*
* Supported but untested:
*
* SELPHY ES20, SELPHY ES3
* SELPHY CP-760 and all other CP-series printers EXCEPT for CP-790
*
* NOT currently supported:
*
* SELPHY ES40, CP-790
* (They use different stream formats, and may have different readbacks;
* I will update this as needed and as I get hardware to test..)
