/* LibMitsuD70ImageReProcess -- Re-implemented image processing library for
the Mitsubishi CP-D70 family of printers
Copyright (c) 2016 Solomon Peachy <pizza@shaftnet.org>
** ** ** ** Do NOT contact Mitsubishi about this library! ** ** ** **
This library is a platform-independent reimplementation of the image
processing algorithms that are necessary to utilize the Mitsubishi
CP-D70 family of printers.
Mitsubishi was *NOT* involved in the creation of this library, and is
not responsible in any way for the library or any deficiencies in its
output. They will provide no support if it is used.
However, without this library, it is nearly impossible to utilize the
D70 family of printers under Linux and similar operating systems.
The following printers are known (or expected) to function with this
library:
* Mitsubishi CP-D70DW
* Mitsubishi CP-D707DW
* Mitsubishi CP-K60DW-S
* Mitsubishi CP-D80DW
* Kodak 305
* Fuji ASK-300
