This is great!! I do want to point out that after I installed the HP LaserJet USB Upgrade my printer was displaying UNSUPPORTED and would not adjust. So I turned it off then on again (while keeping the Upgrade as the default printer) and then wrote the code in terminal and it worked. Thank you for this tutorial..you rock!

I had this problem at work today, networked CP3505 to Windows 2003 server. Perhaps I was lucky, but I fixed it by powering on the printer whilst pressing the green OK/Tick button. This must have forced a reload from the server I guess, but the printer came up fine.

Perhaps I was lucky. I powered off our CP3505 and switched it on whilst pressing the Green button. Recalibrated and came up perfectly.

Hello, I have followed all the steps, and after I add the rfu file, I get a bunch of error messages at the command prompt. IE:

Excellent support!!!!

I installed upgrade via a Mac. After the first try I also got the “unsuppoted file type” message. As recommended by Marcus I went to printing system preferences, deleted the LPR’s in que, and then un-paused the printer. Then it took the upgrade and is working : ) thx
