On Vista we are using the pre-installed drivers for the HP Deskjet 970xci.
In the print dialog if you do nothing except change the colour setting
on the preferences pop upto black and white - ie print in black and white,
not colour, and then press OK/Print an error dialog pops up as follows
Title: Incompatible Print Settings
Text:
There are one or more conflicting settings.
One of the conflicting settings is:
Resolution: 300 x 300 dots per inch
Print Mode : Auto Select
It then offers to resolve all conflicts for you.
Its not clear what this does. The "Advanced" tab then shows these
settings still as above but will little yellow triangles containing an
exclamation mark.
This can be reproduced in wordpad etc .. so its not a problem in our code.
Although apparently if you try to set B&W from code so there's no dialog,
you don't get the benefit of this fix up. Bizarrely our app then prints
the page shrunk, probably because the device resolution is changed to
something different than we expected.
This is specific to vista. All works fine on XP
1) How can resolution and print mode be in conflict in B&W printing ?
2) How does vista (I presume its vista not the driver) detect this conflict?
Knowing this I can do the same ..
