I understand that I can assign different icc profiles and rendering intents to different images when I print multiple images in a single job from qimage.
That is correct. select and right clikc images on the preview or in the queue and choose Custom Color Mgmt Settings.
Is it possible to apply different printer driver settings as well?
No you can't but why would you want to do that anyway?
You say
I would like to print an image with an icc profile prepared for "epson standard (srgb) gamma 1.8
A printer icc profile should not be prepared in that way. By doing that, the printer driver is "managing" the colour when printing the target which is definitely a no-no.
Printer targets should be printed with colour management set to "off" in whatever program is being used and the driver set so colours are not adjusted in any way, ie. "no colour adjustment".
