If your printer is more than a year old, you can probably print Custom Page Sizes.
If you cannot print Custom Page Sizes:
- Check the manufacturer's website to see if they have improved the driver. (A driver is a small piece of software.)
- If you still cannot enter a custom paper size, please contact the printer manufacturer and let them know you need this feature. They have the ability to provide updated drivers, but you need to know that you want this feature.

In the past, all Inkjet printers were capable of printing custom page sizes, but now it is a good idea to check the features before buying a new one, especially from HP.
If your printer software does not support custom sizes, please let me know. There are a few workarounds I can suggest.
