I’ve installed/re-installed my wi-fi connected HP Laserjet CM1415fnw Color MFP multiple times in different distributions and have never required a USB hard connection to do it. I’ve found that the most painless way to do it is to go to HP’s HPLIP site (http://hplipopensource.com/hplip-web/downloads.html) and download and install the most-recent HPLIP .run file (currently 3.15.4). This completely takes the place of running any ‘add printer’ routines through the OS. It walks you through the entire setup/update protocol.
It’s the only way I’ve found that the HPLIP Status Service and HP Device Manager gets installed correctly, can read print cartridge supply levels properly, etc.
I’ve never had a problem completing the entire setup routine over wi-fi.
- Note that there is a CLI dialogue to go through, so it isn’t a set-it-and-forget-it routine.
