* Canon SELPHY ES series print assister

|

|
|
* 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..)
