What are Mailing Services requirements for printing and copying the PTAO card?
For the barcode to be read by Mailing Services machines, the PTAEO card must be printed on a laser printer. White, light yellow and light green paper all work. Photocopies work best if they are copied from the original. Second generation copies should work, but third generation do not. Faxing copies of the PTAO card sometimes, but does not consistently, produce a readable barcode.
