Digital BW, The Print

I guess this is Canon's way of choosing Black Only
(BO).  I recently used my brother in laws Canon
printer (i950?) to do some BW prints, but there was no
BO option in the Canon driver, only greyscale. 
Despite a BW imsge conversion using Irfanview there
was always a warm color cast to my prints, although
the overall quality of the print was very good and
those that saw them seemed to like them.

<<Dear Group  Members,         
    I'm contemplating buying a Canon Pixma  iP8500.  
My sole point of 
hesitation is its abillity (or inabililty?) to  print 
B&W without the dreaded color 
cast.  I e-mailed Canon support,  and got back the 
following reply:
 
    <<The most common cause for a color hue  added to 
a black and white photo 
is because the photo has color information  still 
embedded within the image.  
This tells the printer to use color tanks  to form the

black.  While this can 
be effective, a slight shade of color  can be visible 
and is deemed 
unacceptable from a professional standpoint.   The 
only way to get around this with our 
printers is to remove the color  information from the 
image making it a true 
black and white image through an  image editing 
program.  This will cause the 
printer to only use the black  ink tank allowing for a

true black and white 
photo.>>
