It looks likeyou checked in within 45 minutes of your flight departure. Every airline has the same policy. You must be checked-in prior to that time or they are under no obligation to do anything for you. I know Frontier's policy is to confirm you on the next flight if they have seats available. If not, it's stand-by. So, they offered you the option of printing your ticket so you could try to use it on another airline. Most airlines will accept each other's at face value because it's supplemental income... a passenger they wouldn't have had. However, if Continental refused to accept it that's their perrogative. You can't force them to take it without additional payment.

The lesson is to check-in online if you have access to a computer. If not, you absolutely have to be at the check-in desk checked in prior to the cut off time. Unfortunately, all airlines short staff their counters so it is the passengers responsibility to allow time for long lines and a lengthy process.

I'm not justifying it, but that's the way it is. Your complaint, therefore, is really with Continental not Frontier. Frontier would have to accommodate and compensate you for overbooking their flight ONLY IF you had checked in more than 45 minutes prior to departure for your original flight.
