Are you using appropriate paper?

Do you print data without margins?
- This symptom occurs if a margin is set to none in the printer driver. The marginal areas within the first 5 mm from the respective edges of paper are not printable (for envelopes, the top and bottom marginal areas within the first 10 mm from the top/bottom edge are not printable). Make sure to have margins around the document to print.
