Dear all, I've gotten down to the work of splitting pixma_mp150.c into two sub-drivers.
The major new work in my customized pixma_mp150.c file is: 1) support for 4800dpi scanning for existing supported printers (MP810, MP960, MP970, MP990 --- MP980 not explicitly supported yet) 2) support for the Canoscan 9000F 3) new interleaving of sub-images for the above. I propose that the following devices, which all have 4800dpi CCD capability, be removed from the original sub-driver and supported (fully) but the new sub-driver: 1) MP810 2) MP960 3) MP970 4) MP980 (no specific work done, assumed similar to MP970 or MP990 and to be added whenever testing can be carried out) 5) MP990 6) Canoscan 8800F 7) Canoscan 9000F There are several CIS devices with 4800dpi capability, but these work fine with the existing sub-driver functionality. Furthermore, there are new devices from 2010 which I have added experimentally to my sub-driver which I have been distributing on an individual basis. The results are not known at this stage, but I assume that the CIS devices will work perfectly well with the existing sub-driver. I now added the 2011 devices as well. Of these 2010 and 2011 modes, only the top-range models use CCDs with 4800dpi, and these should be added to the new sub-driver: 8) MG8100 series 9) MG8200 series To avoid breaking existing devices I would like to comment them out in the existing pixma_mp150 sub-driver file, and similarly comment out in the new sub-driver any devices which should be supported by the existing sub-driver. Please let me know any comments, in case they will be helpful for me to get this task done as soon as possible. Regards, Gernot Hassenpflug
