Damn, Google AGAIN sent the notification of Mike's reply to the server's Spam folder despite me previously marking it as NOT spam (I don't normally use web-mail, so rarely check that folder).  I've now updated my ddisoftware.com profile to change to a non-Google eddress that I have some control over.  So, sorry for this delayed response.

Mike,

Today I had a call from an Epson support technician, who explained to me why the R2880 driver (and I'm assuming all their other inkjets with borderless capability) reports the incorrect paper size.  So I came here today to explain it for everyone else's benefit, only to find your far more detailed and perfectly correct explanation!

Many thanks for taking the time to explain this behaviour, and I'm sure others will benefit too from this understanding.  I like your suggestion of setting 'compensating' margins in Qimage, which would solve my edge-positioning problem for multiple images.  I accept that I might get a sliver of white on an edge due to paper-feed misalignment (the Epson tech also explained that), but I only occasionally use this setting when I want the pictures at the maximum size possible for the paper, without losing a few millimetres from the edges due to unwanted expansion.  Trimming off the little edge sliver is minimal area loss compared to what would be lost using expansion.

Thanks again for your excellent and patient support.

Thanks for the clarification, Mike.

I checked the printer 'page size' setting (see screen-shot), and it is set as you suggested.

So I guess I should now be contacting Epson support or a related printer support forum.

Apologies for the delayed response.  I was relying on the 'notify me of replies' facility, but received none.  So I just logged in to my Gmail web-mail (I use Outlook, not web-mail) and found one in the Spam folder, I've marked it as 'not spam' so hopefully will receive future notifications!

Terry, thanks for your reply, but if you read my initial post and viewed my first screen-shot, you will see that, although I have set 'borderless' in the printer setup, I have also set 'no expansion' in the printer driver (as well as in Qimage).

So problem still unresolved.

I'm using Qimage v2009.268 (yes, I know it's old, but it does all I want – when it works – so I have no incentive to 'upgrade').  Today I went to print two images on an A4 sheet.  I pre-sized the images to exactly 148.5mm shortest dimension, and set Qimage for 'Original size', so the two images should meet in the middle of an A4 landscape sheet (297mm wide).

But when I placed the images and opened the Full Page Editor to accurately position them, after setting the left and right margins both to zero, I noticed there was a gap in the middle, where there should not have been.  It was then I noticed Qimage was showing my page size as 303.9 x 215.0mm, which is NOT A4 sheet size (297 x 210mm).

The first screen dump shows that I have set the page in the printer driver to A4 landscape, borderless and with expansion turned off, so the printable size should be exactly 297 x 210mm.  The second screenshot shows I also have Qimage expansion turned off.

So why is Qimage showing an incorrect page size, spoiling my prints placement?

PS: It took me several goes to get my attachments accepted – firstly, the stated restriction is misleading, saying "Maximum attachment.." (singular), so I made sure each of my attachments was under 256KB.  But it seems the restriction is meant to be: "Maximum total attachments size...".
Secondly, 256KB is rather small to attach even two screen dumps to illustrate a problem, let alone where more are required.
