This patch make:

- Users can use quality settings (not so nice way), but
for first....
- the media type, and printing method? fixed for a lot of
type of printers (the BJC-50,55,70,85,210,230,240,250
1000,2000,4000,4100,4200,4300 use these parameters
this way.)
- some color correction for BJC-2x00 and 1000 for BC-06
photo cartridge!! (now, the photo quality is near /or
better than/ windows's driver...)You have to try it!-
a new entry for BJ-230 (I don't know why forgot
before...)

There is an ugly media to media conversion, but not for
ever...

    Could you please email it to the mailing list rather than
    posting it here? More people will see it that way.

    This is almost surely incorrect; it indicates that all three
    drop sizes have the same value (in terms of ink drop size).
    Is that really your intention?

    + static const stp_simple_dither_range_t
    canon_dither_ranges_pY_2bit[] =
    + {
    + { 1.000, 0x01, 1, 1 }, /* value, bit pattern, dark?,
    rel. dot size */
    + { 1.000, 0x02, 1, 1 },
    + { 1.000, 0x03, 1, 1 }
    + };

    I send it to, mailing list...

    Ink drop sizes:

    It is not so important (I think), because this cheap trick
    causes the following: the driver generate 01 pattern for
    the most intensive yellow (a solid yellow area is
    01 01 01 01 01 01 ...) like windows' driver, and I read in
    the new-printer.dvi:
    "The relative amount of ink actually deposited by this dot
    (not currently used for much; it can be used for ink
    reduction purposes, to reduce the amount of ink deposited
    on the paper)."
    If I use a simple NULL for yellow in 'variable ink list',
    the driver produce an 11 11 11 11 pattern for highest
    yellows instead of 01 01 01 ... It may look not too bad in
    printing (I never see...), but may cause an unecessary
    yellow ink deposit.!!The windows' driver use only 00 and 01
    patterns for yellow
    ink!!!

    If you have a better solution, please correct this ugly
    trick...

    This is being discussed on gimp-print-devel. It will be
    done post-4.2.

    Would you mind to update this patch and send it to the
    list? The code has changed quite a bit and this is not a
    unified diff.
