Hi
I am having the same issue. I am using images that I have used 100s of times in photoshop and silhouette and I am trying to change to Affinity to design. I create the image and then when I print I also get random black straight lines. It makes no difference what paper I use either.
If I print the same image from any other program it is perfect. It is not a printer issue as this works fine with all other programs.
If I export the image and open back up in Affinity it prints fine but I am confused as to why this is happening?
Any help would be greatly appreciated
