The problem I'm having is that Qimage now randomly puts print jobs in some kind of poster mode (a little red 1x2 or 2x2 displays in the upper corner of the preview image). I don't want that. How do I reset that so Qimage just prints on shot per sheet like I had it before? Any suggestions appreciated.
The little red 1 x 2 etc. is telling you that the print size you are requesting is larger than the printable area of the paper you selected.
Look above the right upper panel and that will tell you the printable area of the paper size.
Perhaps, select Fit To Page instead of requesting a 4 x 6.
If you want no cropping, then make sure the crop scissors is turned off.
