Q: The printer is not connected

Is the printer connected to the Mac via USB cable or is it networked (WiFi or Ethernet)?

In many cases, simply removing the printer from Print & Scan and then adding it again is enough to resolve this message.

Pahu - Please excuse me for jumping into the middle of another thread, but you seem to be the guru for Canon printing issues.

I have the MF4370dn. I have an Airport Extreme router which is hardwired via ethernet to the printer. The printer is connected via USB to my MacPro running OS 10.6.8. In that configuration, I can print and scan just fine. The LAN connection to the printer is irrelevant since I have the USB connection.

However, I also have a Macbook Pro running OS 10.8.3. Regardless of whether the MBP is connected via ethernet to the LAN or wireless, I can't get it to print at all. It will only print if I connect it via the USB.

I also have a Windows-based laptop that currently can't connect wireless either.

I've gone through multiple iterations of deleting the printers, trashing the UFR folders from the Printers and LaunchAgents folders, stopping the UFR II BackGrounder. and reinstalling everything with the current drivers from Canon. Nothing seems to work.

Please help!

When I click the  +  to add a printer, I do not get a menu of nearby printers. Instead, I get a new window titled 'Add' that has the 4 submenus of Default, Fax, IP, and Windows.

If the printer does not list under Nearby Printers or in the Default view of the Add printer window, then it could be two things - it does not support the Bonjour protocol or if it does support Bonjour, it is configured for a different network to the Mac.

If it does not support Bonjour, then you have to add the printer using one of the IP protocols. You mention trying IPP. This protocol is not always supported or is not always enabled or requires specific queue information. So I would recommend trying one of the other IP protocols, such as HP Jetdirect. This is the default protocol used by Windows so its always enabled by default.

If adding the printer using HP Jetdirect does not work, then it can be due to the printer driver. There are certain vendor drivers that do not support a network protocol other than Bonjour. There are often alternate drivers available, so if you have no luck with adding the printer this way, reply with the brand and model so I can check the specifications.

If the printer does support Bonjour then you need to check that the network addresses being used by the printer and the Mac are correct. For the Mac you can get this information via the Network preference pane in System Preferences. In the printer you can often print a network configuration page that will detail the network settings.

Once you know the printers IP address you can open a web browser and enter the IP address of the printer as the URL. This will connect to the internal web server in the printer (assuming it is relatively new and has such a thing). If it does connect then it confirms there is a functioning connecting between the printer and the Mac.

For the PC and MBPro not to be printing, it would suggest that the configuration on the Mac is not wrong and that you have some other issue, such as machine network configuration.

On the Mac, did you add the printer using the Bonjour protocol? This makes the printer appear under the heading of Nearby Printers in the little pop-up window that opens when you click the plus button in Print & Scan. If it didn't, and you selected an IP protocol, then note that the UFR2 v2.43 driver only supports the LPD protocol. HP Jetdirect and IPP are not supported on OS X.

And if the printer did not appear as a Nearby Printer, or it does not show in the Default Add printer window, then I would be checking what IP address it has acquired (assuming you have it set to use DHCP which is the default). If you enter the IP address into a web browser, do you see the internal web page of the MF? If not, then open Network Utility, select Ping, and then enter the MF IP address and then press Ping. You should get a response to each ping packet sent.

PAHU - I've tried most of the variations you've suggested. The troubling thing is that I can't ping the printer when I give it a manual IP address.

I can see the printer in Nearby Printers if I turn on Bonjour on the printer. However, I can't print to it.  I've also downloaded the V2.34 drivers about 3 times now (each time trashing all the folders you suggeted in another thread), but when I open the Printer Utility, it still shows the driver version as 2.0.

If I try to configure it using DHCP and Bonjour, I get through the setup and then the computer tries to send a Printer Control Command to the printer that I see in the Print Queue. Once that's done, I try to print a page, and I get the error

Canon UFR II Printer Driver

Cannot communicate with the printer, or the printer is not supported. If the printer is supported, check the printer connection and add it again...

The error doesn't make sense because the computer is able to communicate with the printer otherwise it wouldn't appear as an installed printer.

Then you would be setting an IP address in the printer that is wrong for your network. As I mentioned above, for a typical home network, the IP address subnet is the first three numbers of an IP address. The last number is the network address. So each device on your local network must use the same IP subnet, while each device must have a different network address.

Downloading it three times is just wasting your monthly data useage (if you have such a thing). If you are looking at the General tab after selecting Options & Supplies in Print & Scan, then it will only show 2.0. But if you have a document open and select to print and change the print dialog to About (Show Details has to be selected for the print dialog), then this will show the UFR2 driver version.

This error does make sense to me, in that it is something I have seen numerous times, typically after the Mac is upgraded from 10.6/10/7 to 10.8.

Can you open System Information and select Printers in the left column. If this is the only printer on the Mac then the right pane will show information about the Canon device. If you have more than one printer, you will have to select the Canon in the top right pane to see its information in the bottom right pane.

Can you select this information about the Canon printer, copy it and then paste it back here.

The IP address isn't wrong. I can't even ping the printer when I use the address assigned by DHCP, which is the next address in line from the computer I'm using.

I'll put screen images up because it doesn't look like the computer is able to get any relvant information.

If you cannot ping the MF then it makes sense that the Canon UFRII Print Utility cannot obtain any information.

So I still need to see what is set in System Information (located in Applications > Utilities). Can you get me this information please.

Can you also tell me the IP address, subnet mask and gateway (router) address set in the MF and the Mac.

PAHU - Sorry. I was looking at the wrong thing for the System Information you requested. Here is it. It seems to be showing Driver Version 2 and Print Utility Version 2.43.

IP address are:

Printer - 10.0.1.7

Subnet - 255.255.255.0

Gateway - 10.0.1.1

MBP - 10.0.1.9

Subnet and Gateway are the same in both the MF and the MBP

Thanks for the information. It all seems to be correct so there must be some other cause.

Are you still unable to ping the MF or open its internal web page? If yes, then maybe you have some application that is blocking the ping and the UFR2 driver from communicating. Do you have any A/V or 3rd party firewall utility?

No firewalls on the network. And I still can't ping the MF. I can ping every other device on the network.

If you cannot ping the MF then the IP address you are using is not being used by the MF or something is blocking the path. I've seen Intego's VirusBarrier X6 do this. Any A/V installed on the Mac?

If you enter the IP address into a web browser, does this connect to the internal web page of the MF? If not, how are you determining the IP address of the MF? Are you printing out a configuration page from the MF or using some other tool to check the IP address?

I'm not running any A/V on either Mac.

I've got the MF configured for DHCP. So I can go into the menu on the MF and view the IP address assigned.

I also can't access the internal web broaser on the MF by point to that IP address in my web browser. I get a time out error.

So my Apple Extreme router can assign an IP address to the printer, but nothing else on the network can reach that IP address.

My Mac Pro and printer are plugged into the same switch and still I can't ping the printer.
