Tracing paper is a visual cue for users to see the underlying clone source to help in painting on a new canvas/layer and under normal cloning does not save to a .jpg file nor print.
What you have as a cloned image from your painting can best be seen by turning the tracing paper "off"; then you will see what will save to .jpg or will print.
Since your result was a current pattern, you apparently "cloned" not the source image file but the pattern (which is the default if you have no image source selected to clone). And I suspect it was faint and overwhelmed by the visual cue of seeing most of the source because of the transparency/opacity setting of the tracing paper set to see most of the source image. But that does seem odd to have a clone source and paint the pattern???
I suspect you need to read the help file for quick clone and try again step by step.
Alternatively if you wish to effectively use a real tracing paper effect, once you have done a clone, is to raise the cloned/painted image to a new layer (or cut paste onto a new layer) then copy paste your source image from the file to a new layer under the painted image. Result is you have a 3 layer file: bottom is a canvas (empty), the source image layer, and on top layer the painted image. By changing the opacity/transparency of the source image layer it acts just like tracing paper but will print and can be saved (all layers flattened) to a .jpg file. Always best to first save a .rif file of all the layers in case you wish to change something later.
Note: the source image could be on the canvas and painted image on a layer above; resulting in a 2 layer file, but usually "safer" to just keep the canvas available if needed to work with it "uncontaminated" with the source.
If above does not help enough, try again and write here again if you need more help or have more questions.
