I'm sure that Qimage is a very well done software.
I try only to know what is wrong in my pc/Windows/etc. in order to do prints I want.
 

For what I know, Windows programs have not problems with memory.
If a software need memory ask Windows to allocate the requested amount.
Window permit application to use physical memory or, if the amount is excessive, it swaps memory to .... swap file on disk.
With the same amount of memory I open a bigger file on Photoshop without problems.
 

I've done the check.
Appear a little window that says :

Information
Start: 798 MB
Addl: 335 MB
Now: 798 MB
OK

My Windows XP system information tell me that I've a total of 3.4 Gb  of physical memory installed (really 4Gb but XP 32 bit can't use all).
I read also that I've 2.36Gb of memory free for applications (with Qimage loaded in memory).
So I suppose that it's not a problem of free memory in my PC.
About jpeg, as I wrote in previous post, was created with Photoshop CS4.

The image, acquired as tiff uncompressed (1,3Gb), has been opened with Photshop CS4.
Then post-produced and saved in psd format.
Then opened to test this software, resized and saved in jpeg.
Sorry but there are not errors in file itself.
Setting in Qimage are almost simple.
I've printed other images in A3+ and works perfectly.
The compressed jpeg to 130Mb is reading well in thumbnail.
When I set the resolution in printer driver to Maximum, Qimage indicates in resolution 1200 dpi, without force settings.
 

Many thanks for reply Fred, it's a jpeg with sRGB as embedded color profile.
I've noted that with psd there is some problem and I've saved in jpeg.
 

Hello!
I'm evaluating Qimage.
I think that it's a very good software.
Now my consideration.
I'm trying to print a photo on A3+ on my HP B9180.
Very normal task, you will think.
Probably, but with some difference in my case.
I start from a file acquired with my Howtek 7500 from a positive 4x5" at 5.000 dpi (or ppi if you prefer).
I've pixel to print an image at 300dpi as wide as 80 inch.
I want to print at 1200 dpi on A3+.
On the widest dimension I need 22.820 pixel and I resize down (a little) my image.
The file in jpeg compressed is about 130Mb.
Once opened it's about 1Gb.
This dimension shouldn't be exaggerate for Qimage because it simulate (using interpolation) the presence of file like these.
The only issue is that the software don't work with such big files.
I've two different results.
If the file is big too much (I suppose over 500Mb) it display "Image read error" in thumb (obviously no error in file itself).
With good compression the file (jpeg) goes down to 130Mb.
So Qimage display well in thumb and try to print.
After print command, appear a message "Qimage could not load the file : xxxxxxxx Current session aborted" .
So, that's all.
If I want to print a file from my EOS 5D and Qimage has to "create" pixels using interpolation there isn't problem, the software works good.
If I've all pixel acquired of "real information" I can't print with this "Professional" software.
