Hello. I am looking for a new compact printer. As the choice is very large, I would like to use your recommendation. It would be important to me that the printer has a paper tray, both b/w and colour printing, automatic duplex printing and a scanner and that it can print via WLAN. I have now come across the HP Smart Tank models. It is said that the ink should be cheaper with these. Is this true? Which model would you recommend? It would also be important to me that the Wi-Fi access works equally well via Apple and Android. Thank you very much for your support and best regards, Thomas K.
