Most document creation programs ship to the user with paper sizes preset into the print function to allow for quick and efficient printing of your document in the size desired. Due to the many available stationery sizes, not all paper sizes can be included however. A9 envelope sizes are often one of the paper sizes left out of the preset collection. To address this issue, the software manufacturers allow for the creation of custom sizes for printing. To use this function, you only need to input the size of the A9 envelope into the print setup.
