HP Officejet Pro 8620 scan to network folder unable to connect to printer

[jackme]

Hello this product (HP Officejet Pro 8620), was working fine scanning documents to my network folder.

my network folder is on my freenas and the folder and read/writable to anyone.

I had it working fine for the last two years, i opted out of the update notifications as HP had removed an option to use 3rd party ink in the past.

Recently i noticed the printer was nagging me to update which i refused, but i also had update notifications turned off which surprised me since they ignored my request.

I Found out the printer can no longer scan to network folder, in the webserver settings it states "Unable to connect to the printer. Check your configurations and try again.", im not sure what this means, the printer is connected to wifi and it had been working fine, ethernet did not help.

The printer it states "cannot connect to IP address and service name \Hpscans, make sure the remote computer is turn on).

this error occurred when there was an issue but the webserver states another issue and even creating another share does not solve this.

The webserver would state cannot connect to remote computer.

I restored the printer and updated to the latest firmware (FDP1CN1825AR) hoping it would work, no help.

I connected the printer to usb via windows 10 to try solve the issue with drivers and that doctor but it doesnt detect any issue.

I have looked online and changed the Ip address and used googles dns settings (8.8.8.8 - 8.8.4.4) but still no change.

Any other ideas?, the setup is easy to do but now i cant solve this issue, i dont understand why the printer would refuse to work after 2 years of solid performance.

The printer has been succeeded by the 8720 so im wondering if it has been told to reduce features.

Thanks

I have solved the issue, with smbv1 being a security flaw (wannacry i believe) it has been disabled by freenas and other operating systems with recent updates.

so i added this command to re-enable on my server. 

sysctl freenas.services.smb.config.server_min_protocol=NT1

Got scan-to-network-folder working with a shared folder (via smbd) on a Ubuntu Linux box after some fiddling, just wanted to share here what I did to make it work.

Seems like the OfficeJet (a 8730 in my case) wants to do SMBv1 / LANMAN auth.

I found this out after looking at my smbd debug logs.

Add to /etc/samba/smb.conf:

lanman auth = yes

Next, configure a password protected share:

[scanner-upload]
path = "/path/on/disk"
browseable = yes
read only = no
guest ok = no
valid users = scan
create mask = 0660
directory mask = 0770 

Next, add a user "scan", set a password:

adduser scan

Add it as a smbuser (use the same password):

smbpasswd -a scan

Configure the network folder through the OfficeJet web interface:

Network path: \\<smbd server ip>\<share name>

Use user name and password chosen when creating the user

Save and test

If it doesn't work, increate the smbd debug logging to see what's going wrong.

Hope this helps!
