Presently, in popular speech, has acquired something of a future force. I will do such a thing presently means, I will do it, not immediately, but soon. The rendering here was correct in the older English sense of instantly. So constantly in Shakspeare:
“Prospero. Go, bring the rabble,
O'er whom I gave thee pow'r, here, to this place.
Ariel. Presently?

And breathe twice; and cry 'so so;'
Each one tripping on his toe
Will be here.”
Temptest, iv., 1.
