in the last month, I have trouble everytine I want to print. I have a Canon PIXMA MG8120 and a Canon S820.
Both were workin fine before. Now I get the message: "Support Code 300 The printer is not properly connected to the computer" or "The printer is not responding".
If I type the IP address of the printer in Safari and theprinter page opens, the it starts printing.
Is this an Apple problem?
Macbook Pro Intel, Mac OS X (10.5.5)
Your Mac is running which OS X ?? Your profile indicates v10.5.5
Some people have gotten it to work in this discussion.

I have Mountain Lion
The error code is usually a result of the printer losing connection to the wifi access point. One action would be to turn the MG8120 and your wireless computers/devices off and then turn off the wifi access point (router) for a minute. Then turn the router back on and then all your wifi devices. Then see if you can print without error.
Given the S820 has no network port, how is this model connected to your network? Via an Airport Express or shared via another computer?
Thanks for your help. The MG8120 printer is connected by Ethernet cable to the Verizon router. It has a static IP. The S820 is connected by USB to my Apple Time Capsule.
Thanks for the reply.
Could you provide more information about the network you have?
You mention having a Time Capsule and I assume that its wireless service is enabled. Does the Verizon router also support wireless? If not, I would also assume that you are using wireless on your network and you have the Time Capsule connecting to the Verizon router via Ethernet. If so, then I would suggest moving the MG8120 to connect to the Time Capsule via WiFi or Ethernet and have the MG set to DHCP so that it can be allocated an IP address. After doing this you would need to remove the MG from the Mac's Print & Scan preference pane and add it agian.
Hello,
Thanks for your help. My network was managed by the Verizon router and I had all the described trouble with the printers. I created a network with my Airport Time Capsule and everything works up to now on that network.

I got the same message, and in my case I checked the wifi network on my MacBook and somehow it had selected another network (BT free wifi), as soon as I changed it to my home network the printer started working again just fine.
I get the Error Code 300 only when I'm also running a VPN client (like VyprVpn). As soon as I quit the VPN the networked printing works fine.
Support code: 300 The printer is not properly connected ?
