Error connecting to shared printer - unable to verify the printer on your network

Question

Error connecting to shared printer - unable to verify the printer on your network

This question has been asked before, but with no reply, so...

I'm on a MacBook Pro 12,1 running macOS 10.13.6. I have a Brother printer connected to an iMac (via USB), running 10.12.6. The printer works fine on the iMac. It's shared on the iMac to "Everyone".

When I try to setup the printer on my MBP, it shows up in the "Add" dialog as:

Brother HL-L2300D series @ My iMac         Bonjour Shared

When I select it, the "Name" and "Location" fields are populated correctly, and the "Use" field contains:

Brother HL-L2300D series CUPS

So far so good... but when I click "Add" I get an "Unable to verify the printer on the network" error:

I can't find any information in any log about what kind of error occurred. I've tried a bunch of things I've tried that were recommended in other postings:

Removed and re-added the printer on the iMac
Rebooted the iMac and the MacBook Pro
Tried connecting via IP (using both LPD and IPP), which don't seem to find the printer at all (the "Location:" field is empty, and the "Use:" field contains "Generic Postscript Printer"). If I try clicking "Add" anyway, I get a similar "Unable to verify printer on the network" dialog.
Reset the printing system on both systems.

None of these fixed the problem.

Can anyone help?

MacBook Pro 13", macOS 10.13

In Sys Prefs>Network on both, what are the two IPs?

Are the first 3 numbers the same but not the 4th?

Have you tried the Print& Scan App?

Update: I was able to add the printer using the CUPS interface (localhost port 631). But when I try to print, I get the message "Opening raster file failed" (and the job doesn't print).

Still seeking enlightenment... 😜

That's OK, are you running any Anti -virus, Cleaning Apps, or VPN?

The Last number needs to be different, are you using DHCP or Static IPs???

The interface that connects to the Internet should be dragged to the top of the list.

Sys Prefs>Network>highlight the Interface you're using>Advanced>TCP/IP>Configure IPv4: Using DHCP.

Apply.

Just did, it doesn't find the printer, even by IP address. It finds the Brother printer on my other iMac (though it's not supported by the app)

Also, I can print a test page via the printer utility on my MBP when I create the printer in the CUPS admin page. But other attempts to print generally fail. If I print a random file, it hangs on the MBP and the message in the queue on the iMac is "Open raster file failed."

Raster errors are generally with the Driver problems converting, have you tried sending a PDF from the MBP?

Seems like the Print Job is getting transferred if I read you right.

Can you try the Generic PostScript driver on the MBP?

Sorry, I misunderstood...

The IP address of the MacBook Pro is 192.168.0.16. The IP address of the iMac is 192.168.0.24

I was running a VPN, but even when I turn it off, the problem persists 😟

No anti-virus running at least on my MBP... Not sure about the iMac.

In case I hadn't mentioned it, I can print to it remotely from an iPhone or iPad.

With the generic PS driver, I was successful if I printed a PDF. But printing from, say, Firefox, that seemed to fail.

At this point I'm giving up... just not worth the trouble. I'm wondering if the printer drivers are out of date and they're not supporting MacOS 10.13. The printer is pretty old.

Thanks for all your help! Stay healthy...
