Just prior to and now after installing firmware 1.24 I am unable to complete the setup for a Canon MP600. During setup the DPR 1260 sees the MP600 and when it tries to download the required file a browser window opens advising the download can not be found. I have been using an MP600 with the DPR 1260 successfully for the past six months. I also have an Epson R340 connected and it continues to work just fine. I tried going thru the setup process again for the R340 and the download file is found. Are the download files specific to each printer?
