When you open the scan in Gimp you see something like this ? Which one do you consider default quote: I opened it in Gimp and accepted the default conversion.
Do you Keep or Convert ? Which ever one you use try the other one.
Alternative:
A foolproof way (unless the printer has run out of black ink or you want some coloured parts) is convert the image to grayscale
Use Image -> Mode -> Greyscale
Edit:
I once had a Canon inkjet printer that refused to use black ink when printing from Gimp. Black can theoretically mix from cyan + magenta + yellow but in practice with the Canon, came out a shade of brown.
However something else to check.
The Gimp Windows Print plugin is only a front end for your printer software.
Have a look in the Print set up for Preferences which takes you to your printer interface and there might be a greyscale setting somewhere.
I'm sorry. It only asks me to "convert" when i open the JPG file (but i do click convert). The JPG prints in blue as well. The PNG file does not ask me to convert when i open it. I'm using the PNG file for what i need to do. I tried your suggestion of changing the image to greyscale, however once that is done, you can't add anything with color to the image even on it's own layer. I need to add little red hearts to the image. So that won't work.
After your comment about your cannon printer not printing black, i opened another file in Gimp that has black in it, and it prints fine. It seems to be just this file (in either extension). So I'm thinking it must have something to do with how she created the files, but i'm not sure. She takes her sketch, and scans it which produces a JPG. She takes the JPG into Photoshop, makes the background transparent and then saves it as a PNG. Can you think of anything she might be doing which would cause this only for Gimp?
Also, since we're talking about how the file is made, let me ask you something else. When I look at all my other files that I've purchased with transparent backgrounds, has the nice clear subject/image sitting on top of the checkerboard "transparent" layer. When i open her PNG file, it looks like the subject/image is behind the checkerboard transparent layer, if you know what I mean. Is that how Photoshop does it's transparent "backgrounds?" It doesn't make sense to me... if it's laying in front of/over the "image" then it's not the background, right?? LOL. But i digress....
