I think there's some confusion here. You
can use a free-standing CD recorder - if I used the wrong term (burner vs recorder) I apologise... but the point is you can get such machines - search for 'standalone cd recorder' - I used to have one by Marantz, and they accept audio inputs to make a conventional 'audio' CD which can be played in Hi-Fi CD players.
So it's perfectly acceptable to feed the stereo output from the dp24/32 to one of these machines, either during or after mixdown/mastering. Yes the signal will be converted from digital to analogue on the way out of the DP machine, but this isn't the end of the world. I use an analogue mixer when bouncing tracks to & from the digital domain and you'd need to have pretty sharp ears (and equipment) to hear the degradation... and we didn't complain that much when analogue tapes were used so I wouldn't worry too much

My point in the videos with the '19-bounce test challenge' was really to show how this would have been impossible with the old-school cassette portastudios. Doing a one-off conversion when making a CD is not an issue in this context.
However, there are more important disadvantages (imho) which swing the argument in favour of using a computer to burn a CD...
- Recorders are very expensive; as mj said, if you've already got a computer, why buy another bit of gear?
- Recorders burn in real-time, whereas computers can do it faster.
- You only get one shot at recording so if you get it wrong, the CD is wasted, e.g. if the playback and/or recording levels are wrong, or you don't synchronise the start of playback with the start of recording, etc.
- Difficult to make multiple copies; you'd have to manually press buttons as above so each CD would be slightly different, whereas a computer could make perfect replicas.
- Limited ability to create or move track markers around.
- Limited ability to create CD-Text.
I would get that stereo master file copied from the sd-card to your computer, check it plays ok using a standard media player program, then tackle the issues about what you want to do with the file. If you want to make a CD, use a program to make an Audio CD (not a Data CD) - this is what mj meant by authoring. If you want to email it, use a file-sharing/transfer site. If you want to upload it to a music service site, see if it accepts the wave file as-is, if not, you may need to convert it to mp3, in which case a tool like Audacity would help - the exact process depends on the tool but it would something like: import the master wave file, then export it in the reqd. format.
