I setup a LR3 preset to do that but unfortunately it creates a TIFF in the LR library rather than a temporary TIFF file to pass to Qimage. That means there's another file to delete in LR once the printing is over.
I'd much rather it created a temp TIFF file.

In order to avoid the large TIFF file, I created an export preset with JPEG (100%) as the output format and Qimage to open once the export has been finished. Works similar to setting Qimage as an external editor.
I could improve the printing quality from Lightroom by setting the resolution to 360 ppi (recommended for Epson printers). I had forgot that and was printing initially with 240 ppi. With that setting the prints from Qimage are still better (especially watermarks) but the results are much closer.
Kind regards
