No scanning possible trough router with Wifi Printer

[Stardust]

Hey all.

I have a ASUS AC68U router with Merlin's 384.7 and HP Photosmart 6510 all-in-one.
I used to have no problems when scanning and printing with Linux Mint 18.3Cinnamon.
Now with 19 Cinnamon, I can print OK, but my PC's can't see the HP when I try to scan??

I got this message when I try to use "simple scanning":

HPLIP cannot detect devices in your network. This may be due to existing firewall settings blocking the required ports like (5353/udp). When you are in a trusted network environment, you may open the ports for network services like mdns and slp in the firewall. For detailed steps follow the link.

I don't know this is the right forum to ask, but right know I simply have no clue after searching the Net..

What do I do now?

Regards

John

The issue may be that Mint 19 does not support SMB1 out of the box.

I found this link: https://forums.linuxmint.com/viewtopic.php?t=270442

tried adding this

client max protocol = NT1

And rebooted as suggested, did not help.

One thing: With USB, scanning and printing works, but I want to continue to have the HP all-in-one in another room.

Is Ubuntu 16:04 really better than 18:04 regarding this??

With Ubuntu (and variants) and HP printers - use CUPS instead of Samba to access the printer... CUPS should pick it up automatically, and same with the various scan tools...

Tip on HP - set it to a fixed IP in the printer WebUI rather than DHCP - use an address outside of the router's DHCP scope/range..

The printer part works fine with CUPS and Wifi ..
The scanner part - not so much ...
Well I have found a page, that explaned the some bugs that has been since 2017 has not been fixet.

See this:

sharing a network HP aio scanner is not possible due to bugs 807427 and 838212. Network scanners from other vendors might work in sharing mode though.

Even with Windows - setting the printer to a fixed IP generally fixes the HP software that they provide for Windows desktop...

I had issues with both Win7 and Win10 with the HP - finally swapped it out for a Brother MFC inject all-in-one, and it'll be a long time before I look at HP again...

Brother all-in-one? Well that is something to check out - thanks for the tip.
My HP are not new anyways, so no tears ...
