While @Badr Bellaj's answer is correct, here is an alternative way that will also work after you generate your account and restart your browser.

Download that UTC-... file which is your private key encrypted with your password (you've already done this). Then go back to MEW and select View Wallet Info > Keystore file (UTC/JSON) > enter your password. That page will show you all the information which you can print out any time you want.

Generate New Paper Wallet

Here are the steps to create a new paper wallet that contains your public address and your unencrypted private key (to be kept secret) using https://www.myetherwallet.com/:

  1. Go to https://www.myetherwallet.com/.
  2. Ensure that "MYETHERWALLET LLC" is displayed next to the green lock icon. This ensures that you are not being attacked via phishing or man-in-the-middle attack.

  3. Enter a password.

  4. Click the Create New Wallet button.
  5. Click the Download Keystore File (UTC / JSON) button.
  6. A file with a name of the format UTC--<date>--<address> is now saved on your filesystem. An example filename is UTC--2017-12-05T16-48-22.864Z--dd7d0aff035936edde52e7481aebbc527a3bd944. Here is an example content of this file.

    {
      "version": 3,
      "id": "144a3fbb-166a-4812-8994-7fbb67453288",
      "address": "dd7d0aff035936edde52e7481aebbc527a3bd944",
      "Crypto": {
        "ciphertext": "fb0396c0b6629232236bc66ffc87ed2390725902f3cbd9cbece3a67a36b27b0f",
        "cipherparams": {
          "iv": "545695ada7f16fbb5b0c0be4d9c57306"
        },
        "cipher": "aes-128-ctr",
        "kdf": "scrypt",
        "kdfparams": {
          "dklen": 32,
          "salt": "25e69b30c724629e5abcd68486f20e45fb13e58fb088d06dd9f2caeec9b1d6b9",
          "n": 1024,
          "r": 8,
          "p": 1
        },
        "mac": "d299ae9a17717611c89101039a64a39e1b701efface8e2025eb3c6634129cdef"
      }
    }
    

    Caution: Never share this keystore file with anyone!

  7. Now click the "I understand. Continue." button

  8. The private key is now displayed. You may save this private key. Caution: Never share this private key with anyone! If you choose to save this, save it securely such that it cannot fall in the wrong hands.

  9. Now click either the Print Paper Wallet button. This gives you a paper wallet that you can print on paper and save it in a secure physical location.

    Alternatively, you can just copy your address and your private key and save it wherever you wish. Note that the private key should be saved in a secure manner such that it does not fall into the hands of the wrong person.

What Must Be Saved

Note that you need to have at least one of the following to recover your wallet in future:

  • The keystore password entered in step 3 along with the (UTC / JSON) file downloaded in steps 5 and 6.
  • The private key (displayed in step 8 or step 9).

The above requirement is clarified further in the following points:

  • If you forget the keystore password, you cannot recover your wallet with the keystore file.
  • If you do not have the keystore file, you cannot recover your wallet with the keystore password.
  • The keystore file must be used with the keystore password to recover your wallet.
  • If you only have the private key alone, you can recover your wallet, i.e., if you have the private key, you don't need anything else to recover your wallet. The private key alone is sufficient to recover your wallet.
