I bought the CP800 me a year ago and was really pleased with the. If you have calibrated the printer, makes the very good results. The CP800 I have often taken at events and photos printed on my Android tablet via Bluetghooth on the printer. This approximate Polaroid effect is great already, only takes the term (with opt. BT dongle for the CP800) or sending by BT quite long. Thus, the changes now on the CP900, hoping that this is going faster than before. Yesterday, the CP900 has arrived and in direct comparison with the CP800 I'm partly disappointed. When unpacking it occurs to me that's the CP900 lighter than the CP800. The CP800 feels somehow-quality and robust. As already mentioned the previous speaker, the CF slot is missing. Also, the optional Battery Pack NB-CP2L can not be fixed directly to the housing. Desperately I had to read that you have to buy a specialized power supply here, which suggests here with 99Euro at Amazon to Beech in the instructions. This is really solved times stupid! I connected after unpacking both printer to my computer, compared print speed and result. Print speed is the same, printing results (both printed without calibration) has the CP900 a slight yellow tinge. The CP800 color I like a little better, just falls out of something dark. This can be correct but easier as a color cast. Remedy will certainly bring the calibration here. The CP900 is bound as with cable as fast with the wifi connection, so extreme advantage at this point. After the computer test I then tried on my Android tablet to print and had already notice a big disappointment again. The Android app is not ready yet and will probably only end in December Google PlayStore be available. The CP900 is advertised but quite different from that already this all works. Here I feel a little kidding. The CP900 has indeed but if you print a lot more opportunities to internal settings from a PC or MAC, which one may also matter. So who seeks such a printer and wifi not necessarily required, I would always advise to CP800, one gets here at Amazon for 70Euro. But I will keep the CP900 the first time now, I just hope the AndroidApp works and coming soon!
Addendum on 27/10/2012: Since the Android app yet is so ready I must rely on my BT dongle that works the CP800 without problem. Unfortunately, I realized that the not compatible with the CP900. What shoud that? Now that's really sobering ..... That's why I can for as a half-baked product also awarded only one star ... a real shame!
