Saving a draw point to point drawing from a photo

[mu41]

I am using paintshop prox4 ion Windows 10 home. Just finished creating a draw point to point line drawing of a photo onto vector1 with the pen tool. I had "connect segments", "show nodes", and "create vector" checked from the start. I saved the project as a jpg and gif and when I opened the projects they were just a blank white page with no outline. Then I saved as a png and I opened it was a solid black page. How do I save it so I can see the line drawing? Also I was told that when I save it (which I must not have done correctly) the nodes (little squares) will automatically be removed and just the lines will be seen. Is that true? If not, how do I remove the nodes (little squares), while keeping the lines (so I can make a drawing from the lines)? Thank you

Is it possible that when you drew it, the stroke thickness was 0? You would still see the "path" even if the line was 0 in thickness which can be misleading.
Unfortunately, if you saved in any format other than .pspimage, you can't edit or recover that path you drew.

I am not sure about the black image though.

Thank you so much! The line thickness and the format were the problems. It now prints just fine. Thanks again!
