Is there any chance of a Qimage export plugin for Lightroom that would allow printing directly from LR without generating intermediate files, as when the "edit in" option is used?  I find that the LR Print module is inferior to Qimage, and don't like the extra files generated with the "edit in" option.

Well, two sources.  The ones for the HP papers came directly from HP.  The ones for Red River papers came from the HP printer users forum.  I didn't know profiles could only be used in the driver.

First off, this is probably not a Qimage problem as such.  I get similar results from LR 2.4 when I allow it to manage colors.  I turn off printer color management by setting the "Application managed colors" option in the printer driver and select the proper printer/paper profile in Qimage Studio.  The resulting print is horrible - weak color, no reds, looks almost like a grayscale, except greenish yellow.  If I allow the printer to do color management and turn it off in Qimage, I get a pretty good looking print.  It seems to me I may be getting double profiling in spite of using the printer option to disable color management.  The OS is Windows Vista Home Premium SP2 with Qimage Studio 2009.266 and current HP software/driver.  HP tech support was not helpful.  Any suggestions?
