Hello @ashipratap,
Welcome to the HP Support Forums. I understand that you are trying to print odd and even pages with the HP ePrint app.
The options when printing from a mobile device is limited compared to printing from a computer.
With the app, you can change the page range. For example is you have a ten-page document and wanted to only print pages 4-9 you can do this. If you want to print pages 2,5 and 7 you can't do this at once. You will have to go into the app, open the document and print each page that you want individually.
Please call our Cloud Services at 855-785-2777. If you live outside the US/Canada Region, please click the link below to get the support number for your region. http://www8.hp.com/us/en/contact-hp/ww-phone-assist.html
