There must be something going on that we are not aware of 
Why not take Fred up on his offer and send him an image.
Terry

Just to bring some of the thread up to date as others are following too, I printed your image to Epson Prem Glossy and again to Ilford Gallerie Smooth Gloss.
Both prints are perfect. Your shot is excellent. I see as clearly as can be: The trousers (where you said was dark and no detail) have a stripe and wrinkles. The dress is white as can be without being blown out for detail. The dress looks gray? If anything, it's a skinch overexposed, lots of detail in the lacey part, but a spot here and there on the border of being blown out, so certainly no gray dress.
Again I harp on the driver settings because if we have the same printer, same image, same ink, same paper, and same software, and you do not have some filter turned on like a print filter that you made and have checked the box, bottom right of Qimage, then we must get the same prints.
If we don't, and yours are messed up being too purple, too dark and bad flesh color, we have to suspect the nozzles.


ElJay,
You give me concern when you print with Prtr ICC turned to OFF.
That's where the printer profile goes, and so that the profile is in control of the color, we turn off any interference to the color by the driver by checking NO COLOR ADJUSTMENT.
I am certain that you have something not set right.
Let's drop any reference to the monitor because at this point we are actually looking at prints on paper, right?
I don't mean to sound snippy, but believe me I have been down this road before where the person I was helping never actually made a print to paper. He was comparing soft proofs.
That wont fly.
We are printing to paper.
Do you have the quality set to Best Photo?
You have selected the correct paper in the driver?
You see 720 x 720 above the upper right panel  where it says page size?
Don't dismiss the ink nozzles as not being clogged even though you get a visible pattern on a test. The prints that you like were made on different printers.
Let's work this through.

Fred

With water on that few thousand miles apart!!  

Eljay,
I mailed the prints to you this morning.
I hope you will get them by Monday or Tuesday.
I send stuff to Terry in the UK and it gets there in 4 days...

Let us know what you think.
Fred

You are correct!
The driver is to be set the same as it was when the profile was created; but that is why we are insisting that he use the PGPP paper in the driver, No Color Adjustment in the driver, and Best photo Quality (which is the 1440 dpi output selection).The rendering intent is usually a suggestion, but not a rigid must!

So effectively, it turns out simple.
Select the correct paper from the list in the driver.
Set to Best Photo
Set to No Color Adjustment.
The profile is selected within Qimage.... Bingo!
The most difficult part is to download the profile package for your printer, and to know the names of the profiles so you don't choose one of those EE_233.icc profiles.
His profiles all start with SPR1800.
Then Print!  No softproof judgements.

Once we get excellent prints for LJ, then we can discuss the quality settings for RPM, and rendering intent and what to expect!

Fred

When borderless is set in the driver, the reported resolution is increased due to the expansion/overspray created by the driver.
I assume that is the case here; I don't think is effects the density of ink that is laid down.
Terry

Set borderless in the driver and you get a bigger value - it comes from the driver, not Qimage.
If it is 753,, which I doubt, it is an odd number. Max expansion for borderless on my R800 gives 740 ppi.
Terry

Ah, right, got it now. But how does that fit with the native printer resolution of 720dpi, particularly with resizing?  Anyway, going a bit away from the op's problem,  I expect, so best sort that out first.

Best wishes,

Ray

I should add, (because I have nothing else to do anyway) that most of the larger Epsons like the 3800, 4000, 4800 and 7800 etc, default to 360 ppi. (You can select 720 in the bigger printers by going into "Quality, and putting a check in FINEST DETAIL. That will cause the printer driver to request 720 ppi. Comes in handy.)
The correct assumption being that you are probably going to print a large print maybe roll paper, and 360 ppi is plenty since you aren't going to look at the pring from a foot away from it.
The file size that will be sent to the spool will be huge anyway, but at 720 ppi it will be 4 times larger.
You might reach the limit of your computer resources.
Here's an interesting doo dad. Suppose you had stitched together a group of panorama shots and the image size was really huge ( 24,000 x 3400), and when going to print this at 720 ppi, the print file was over the limit. All you need to do is tick the little arrow next to Resolution Printer lower right area of Qimage's main screen, and change the 720 to 360.
That's why Poster below Resolution Printer already says 360...
It suspects that your poster will be large and will be happiest with 360 ppi.
