I understand that the printer colour management is turned off but does it also turn off the image colour management? What I mean is is that even with printer colour management turned off, if your print targets have a colour space embedded in them like Adobe RGB or whatever won't the colours be printed wrong or at least inaccurately to create a profile?
in edit/preferences/colour management/image imput if I have the 'honor exif colour space if no icc profile is embedded' set up wrong then won't qimage automatically assign the target a colour space before it goes to the uncolour managed printer? I thought that it was essential that the target image remained untagged.
Does that make sense?
thanks

I thought it worked like this (and I wrote this not that long ago in another list):
Qimage has 3 main choices on color management:
1/ CM-Off = Qimage doesn't convert the file, sends the plain RGB data to
the driver so with the color space profile stripped from the file.
In that mode it will also not assign a colorspace to an untagged file,
for example a target file for profile creation. And Windows will not
assign a profile either, it leaves that task to applications.
2/ Let printer manage color = Qimage does the above but the color space
profile isn't stripped from the file so the printer driver CM can do
something sensible with the file.
3/ Qimage CM on, Qimage does the conversion and sends the converted data
to the printer driver, expecting that the last's CM is set to Let
application do CM, so in fact with the driver's CM off..
In both 2 and 3 Qimage could assign a colorspace to an untagged file
based on EXIF data, camera model as an educated guess or without any
hint available it will assign a color space, the default sRGB or a
preferred choice of the user, say AdobeRGB or nothing if the user
doesn't like guesswork.
The printer driver has usually two choices: let driver do CM and the
other one let application do CM. With appication CM set the driver will
do no conversion at all and expects that the application does the work.
That is also the setting you will use to transfer targets through with
Qimage on CM off. When the driver does CM it will expect files with
certain colorspaces, my Z3200 can be set on AdobeRGB or sRGB, the PS
driver has more spaces. The conversion happens to LUTs in the driver so
not with ICC profiles.
