The installation went smoothly, except for the fact that the automatic download of the driver does not have the HP ePrint tool worked. This I had to download on the HP website manually.
First of all, something very important: the printer is completely silent in standby. When performing a print job it is of course clearly audible, but little as 25 seconds later again silently.
The print quality is very good, am completely satisfied. I have not printed photos, because I do not need this.
Have the printer on the network (Win 7 64bit) installed (LAN) and be used in addition ePrint on iOS (iPad Mini) and Android (Samsung S4) both work fine. I particularly like that the configuration of the printer, after entering the IP address in the browser must be configured on an interface and also the toner level of each toner is also displayed.
About money when printing I can not say precisely, but for me as an absolute little printer that will certainly be manageable.
As a truly single complaint of odor (perspiration) should be mentioned when printing. This is of course unavoidable and something not make inkjet printers. At first a bit of getting used to, but as long as you do not sit right next to it is certainly unacceptable. In addition, the ePrint app shows immediately after installation, that the toner may be empty soon. A look at the interface in the browser indicates that the message is nonsense. So a bug in the app seems to be.
