This is not a Qimage issue.  Are you using a mirror border?  Look at the very bottom of your image and you'll find one or two horizontal lines that are slightly lighter in color.  When you print, that will be reflected in the print.  Other programs may not have enough detail/resolution to show it.

Post the image.  That line is in your image.

OK.  I see.  That's why I wanted the image: because I can't really tell what is what from seeing a small corner of a print.  Initially it looked like that side of the image already had a tan border as part of the image and you picked that color as your border to extend it.  In this case, if that whole tan bar is border, it is definitely not Qimage!  When Qimage prints a border, it literally sends a solid rectangle of one color to the printer: it is one statement/call to the driver that says "print a rectangle of this color at this size/location" so there is no way Qimage can print a line inside it.  If your printer prints a line inside that border, it is the printer/driver.  What printer are you using?  Bring up that same job that you printed from the automated job log and once it loads, turn on print preview in the driver and print it again so you can see a preview on the screen before it prints.  Zoom in on that print preview and you will likely see no line there, proving it is the printer.

Just the way that line appears, it looks like a printer issue, possibly with ink delivery close to the edge of the printed area.  It is irrelevant that another software doesn't produce a line: other software may be printing at a lower resolution, slightly different (RGB) color, etc.
