What is the phrase 'pleased to meet you' when translated from English to Japanese?

Hajimemashite

or

Domo (<--- very casual)

or

Dozo yoroshiku or Yoroshiku onegaishimasu (<--- formal way. If you want to say it in more casual way, you can say "yoroshiku" or "yoroshiku ne.")

(Written by a different person than above)I was taught Yoroshuki o-negai shimasu.
