Bought an HP printer to act as backup, but can't figure out how to install it in Linux. I didn't realize it would be wireless ONLY! (And I thought HP was foolproof!) The Yast installer can't find it. I went thru the Windows setup routine when I got it, to make sure the wireless crap works, and it does, with the wireless/wired router. Printer is DeskJet 2755e. Somewhere along the line I asked whether the printer was compatible with Linux, and was told it is, but their install routine only mentions Windows and Mac, as usual.
But the HP support site will give you the instructions for Linux. Google: HP DeskJet 2755e linux <https://support.hp.com/us-en/drivers/selfservice/hp-deskjet-2700-all-in-one-printer-series/29378157/model/29378213> Don't go there, you do not need it.
YaST can't find it.
As I mentioned the other day in another thread, the firewall blocks printer discovery messages. Probably disabling the firewall temporarily will work. Anyway, just tell YaST the exact IP where the printer is.
I'd probably have a hard time returning it, since it was encased in form-fitting plastic! If it's any help, nmap shows an unknown device. This is definitely the printer, since it no longer responds if I turn it off.
Nmap scan report for 192.168.0.103 Host is up (0.0043s latency). MAC Address: 14:CB:19:62:68:71 (Unknown)
Try specifically scanning port 9100, as I said the other day. nmap -p 9100 -n 192.168.1.0-255 Or, more generically, nmap -n 192.168.1.0-255 It will probably also respond on port 80. Anyway, to you can just search for the manufacturer of that MAC address, "14:CB:19": https://maclookup.app/search/result?mac=14CB19 It is an HP. Just enter in firefox: http://192.168.0.103 and you should get the printer web page (unless it is disabled in the printer own panel).
Will try and call HP on Monday, but experience tells me that whoever I get will know nothing about Linux. Any HP wireless guru out there?
As Masaru Nomiya told you, you need the updated drivers in the 15.3 printing repo. Now, DO NOT try to use firefox to download the drivers. I explained the other day how to add a repository, so find that email and follow those instructions to add this repository. Then install, using yast package manager: yast2 sw_single the hplip rpms, version 3.21.4 -- Cheers / Saludos, Carlos E. R. (from oS Leap 15.2 x86_64 (Minas Tirith))
