I have e-mail support about this but hoping someone else can help. I keep getting the error "We’re sorry, an error occurred while preparing this print. If the issue persists, please contact us at firstname.lastname@example.org with details about what’s causing this error to occur.”
I was trying to print out an iPhone stand for my daughter and kept getting this error. I thought maybe there is something wrong with the file, so I decided to try printing out one of the images they gave and still get the error, so it doesn’t appear to be a file issue. I was trying to print out the “Gift of Good Measure Keychain” as a test. I’m using ProofGrade Medium Draftboard.
