outside the country and couldn´t find the correct ink cartridge

[bibmazur]

I have a Deskjet 3755 which uses cartridge #65. However, I´m outside US - currently in Brazil - and this ink cartridge is not for sale here. I bought one which was supposed to be compatible - # 664 -, however, the printer didn´t recognize this cartridge. 

What can I do?

Please look at the following table

Ink cartridge information for HP DeskJet 3700 All-in-One Printer series.

Ink cartridge description	North America and Asia Pacific (excluding India, China, and Indonesia)	Western Europe	Middle East, Africa, Latin America, and CIS	China, India, and Indonesia
Black ink cartridge	HP 65 Black HP 65XL Black	HP 304 Black HP 304XL Black	HP 123 Black HP 123XL Black	HP 803 Black HP 803XL Black
Color ink cartridge	HP 65 Tri-color HP 65XL Tri-color	HP 304 Tri-color HP 304XL Tri-color	HP 123 Tri-color HP 123XL Tri-color	HP 803 Tri-color HP 803XL Tri-color

That means you have to buy HP 123 in Brazil BUT you need to use the following instructions to be able to use HP 123 cartridges otherwise they won't work
