Income call
For income on HPQ you already hold: sell the Oct 16 $40 call and take $38 now. If HPQ climbs to $40 by Oct 16, your 100 shares are sold at $40, so only do it if you're happy selling there.
If it climbs past $40 your 100 shares are sold at $40 and you keep the $38. That is the trade working, not a loss.
