The HP was easy to set up
12 January 2017
Replacement for a Samsung CLP-315W which died after 7 years. The HP was easy to set up, especially on my iMac. Bit more fiddly on Windows 10 running in a Virtual Machine but got there eventually with a driver download. Reading other reviews, some people seem to have problems with getting a reliable WiFi connection. I strongly recommend setting a static IP address for the printer. This means accessing the printer web interface. If you don't know the existing IP address which can change periodically with the default DHCP configuration, check in your router settings to find the IP address the printer is using. It might be 192.168.0.26 which mine kept taking during initial setup and testing. To set it to static, access the printer web interface by typing the IP address into your browser, then select 'Networking' then 'IPv4 Configuration'. Change 'IP Preferred Address Method' to 'Manual', enter your preferred address into 'IP Address' then click 'Apply'. You now have a permanently fixed IP address, reliable and no possibility of conflicts.
Another little quirk I found, when all seemed to be working fine, was inability to access the Web Services, Apps etc. on the printer. The cure for this again lay in the web interface because the default installation didn't set DNS addresses. Again, go into router settings and make a note of the first DNS address. Then back to the printer web interface. This time 'Networking', 'Network Identification' and set IPv4 DNS Primary and Secondary to the address you got from the router. Mine initially said 'Not Specified'. Without an address there is no prospect of the printer being able to access the various web services. This got everything working - Apps, Google Drive, eMail printing etc.
Early days, but everything about the printer seems fine. Like others, I'm a bit concerned about the cost of toner. The Samsung genuine set cost around £150 and all had to be charged for the printer to work at all - in other words if one of the colours ran out you couldn't just print in b/w. which it seems you can do with the M25dw if the colours run out first.
The web interface is very comprehensive with a vast number of options, many more than appear on the little touchscreen so if you're having problems the solution might just be in there.
