it does take a little getting used to and letting the program learn, it will pop up and ask you do you want to let such and such connect to the internet you will likely know what is asking because you are trying to use something that needs access so in those cases say yes, if it is something that needs to access it regularly like your antivirus check mark where it says remember this so it does not ask each time. Do not give server rights some things will ask but it is not necessary once you say no to server rights it will next pop up asking for access, that you can allow. If it is something you do not recognize asking then say no and see if you can determine what it is, if you had some type of malware that is trying to phone home you would not want to allow that access. I prefer mine to pop up and ask each time with some of the rarely used stuff I like to know what is connecting. When getting zonealarm or any other free firewall or any program actually be very alert during the install period and uncheck or do not allow the addition of any toolbars or extras, Zone alarm unfortunately now does try to include a toolbar with the free version, you do not want that toolbar. and if you have problems or questions just ask. When something like generic win 32 something ask for permission say yes or you will not be able to connect to the internet, that is one to check mark always allow. Yes as grandms said with cable you have a direct connection and with no router in between you and the internet that even more dictates the use of a software firewall. The benefit of a router with built in hardware firewall is great but I use both on my windows machines, actually my linux has guarddog firewall built into it so I even have one on linux. The link I had provided the main reason I do refer that link is that there are such good instructions and pictures for someone new to firewalls.

Try googling for Canon plotter forums e.g. "Canon W6200 errors", I have found one link that might be a good starting point. I had a similar problem with my Canon printer printhead and found numerous forums explaining how to reset / fix various error messages. Mine was simply a case of pressing the various printer buttons in the right sequence. Colin Here is a link that might be useful: www.FixYa.com

Thanks, team! :-) I tried the update this morning, and it didn't do anything. But I think Dees may be onto something. I remember when I moved the printer a bit to get at the connections in back, it made a jerky "on and off" type sound that I think would be compatible with a loose connection. I tried to check the printer-computer connection this morning, but didn't succeed very well. In the process I managed to disconnect one of my monitors, but somehow restored it. With two monitors, the laser printer, my big photo printer, the flatbed photo scanner, and three speakers (yes, I have a long desk--it also holds my ham radio), a lot of wires are plugged into that computer. I'll ask my son--who plugged them all in--to check the connection for me.

Are you using wifi, or is it connected with a cable? FWIW, I have a Canon MP270 all-in-one and it's been working fine for years. I thought I lost the ability to use the scanner when I updated to Mac OS13, but figured out how to do it using the system settings. Mine is wired in, not on wifi. One thing that I did figure out awhile back was that there were 3 different Canon printers listed in my system and only one was correct, so when I selected the wrong one in the dialog box, nothing would print. I had to figure out which was the right one and remove the others from the system settings.
