This is already built into Qimage.
Open Qimage, click Utilities, select File Manager, Photo Editor setup.
Put your Photoshop exe file in there for the editor Something like (C:\Program Files\Adobe\Photoshop CS4\Photoshop.exe)
You get it by browsing for the correct file.

To use this interface-interaction, simply right click on the selected thumbnail (s), and select Send to Photo Editor.
CS4 will open properly, do your work, and after a save, close CS4, and Qimage will reappear with an OK box to be clicked.
Click that. All it really does is refresh the thumbnails so your newly saved PSD or Tif etc will be there.

Let us know if you need more.

Sorry, but Qimage is not a Photo Shop plug in. It still stands as the best printing software you can get, and believe me and thousands of others using Photo Shop etc, it is well worth that extra save in PS to achieve the best prints.

Best of luck

If you're using CS4 and Bridge, you can drag Bridge thumbnails directly into Qimage or even drop them into the QI icon.
You can even set up a shortcut to Qimage to link to different printer profiles.  I have an icon for my favourite printer and parer sizes - I simply drag the Bridge thumbnail(s) onto the appriate icon - works great!
