Status update: I've split the driver very basically for now. The new driver is called pixma_mp810.c, since that is the lowest numbered MP device I added full (4800 dpi) support for there. I've removed all other devices from it, save for those listed below (MP810, MP960,970,980,990, and the Canoson 8800F and 9000F). Added pixma_mp810.c to the following files: 1) backend/Makefile.am 2) backend/pixma_common.h 3) backend/pixma_rename.h I haven't yet looked at adding/updating any documentation files. Compilation works, so I will clean up the code a little, and prepare a diff of the pixma_mp150.c over the next couple of days, since there may be a few other changes I had made to existing supported devices that could be not committed in git repository yet. If so I will submit those diffs separately later. Comments welcome.
