First of all, thanks to all who replied, and for all your suggestions. I've been ill the past two weeks & was unable to  reply further. Since I've been home, I tried all suggestions and finally  discovered that  the default color controls in the Epson driver simply don't provide enough tint to be noticeable on my printer, with my paper, and in my viewing conditions, I settled on Sepia, Dark, H=75 V=0. these give me a very, very subtle sepia tint, but at least now, it is noticeable, and I can tell the difference between Sepia & B/W prints side by side. If I need a darker tint, I'll do it in PS and print using the Epson Color Mode. Again, many thanks for your help.

Ernst - thanks for your reply, here's what I did:

In Qimage:
1. Load greyscale TIF image.
2. Select "Let printer/driver manage color"

In Epson driver:
1. For Media type, select "Premium Glossy"
2. For Color, select "Advanced B&W photo"
3. For Quality Options, leave everything unchecked
4. For Mode, select either "Automatic" or "Custom" , result is same
5. In Options, select "Sepia"

At this point, the QI image preview is B/W
Select Print
Epson print preview is Sepia
Print is beautiful B/W.

Here's something interesting, perhaps a clue? When the Epson Print Preview is on screen, if I select "Color Controls" I can change "Color Toning" (neutral,sepia,etc.) and "Tone" options,(normal, darker, etc), the Epson print preview responds correctly, but the print is still B/W.

I can't seem to print a sepia-toned image using Qimage Pro, Epson 3800 and Epson ABW mode.

My system is Win7 64, CS4, calibrated monitor. latest Epson driver. The image is sepia-toned, in RGB mode, the image profile is Adobe RGB. I can get a beautiful sepia-toned print using Qimage and COLOR mode in the Epson driver. I can get a beautiful B/W print using Qimage and ABW mode in the Epson driver (with or without sepia selected in either auto or custom). But I can't get a sepia print using Qimage and Epson ABW mode. Any ideas? I tried converting the image to greyscale mode, but that didn't work either. Maybe I should just stick to the modes that work for me, but I'd sure like to see what the Epson ABW mode can do with sepia.

In all other respects, QI works wonders, thanks Mike  .

Thanks for your help,
Jack
