Thanks for posting in the Apple Support Communities Jael54,
Try the following steps to see if they provide a solution for you:
1: Open the app that you want to print from.
2: To find the print option, tap the app’s Share button or or the Actions button.
3: Scroll down and tap the Print button or Print. If you can’t find the print option, check the app’s User Guide or Help section. Not all apps support AirPrint.
4: If you have more than one printer, make sure the printer you expect to use is selected.
5: Tap Layout, and ensure it's not set to black and white.
6: Tap Print in the upper-right corner.
Use AirPrint to print from your iPhone or iPad
We hope this helps!
