Comcast may have it online at https://www.xfinity.com/learn/channel-lineup or https://www.xfinity.com/support/local-channel-lineup/, although the format is far from ideal for printing. A lineup may also have been included with one of your recent bills -- check https://customer.xfinity.com/.
Service Centers should have printed channel lineups. Check locations and hours at http://www.xfinity.com/support/service-center-locations/ to pick one up, or call Customer Service at 1-800-Comcast and have them send a lineup to you.
The link to the "local channel lineup" does have a "Print" option in the upper-right. It formats it as 3 columns. Mine came out as 3 pages long. It looks like this when I had it printed as a PDF, then opened in Acrobat:
Thank you for giving the print information, I did not realize I would be able to print in a three page format, after going to the print menu.....After calling Comcast, and chatting with someone in an overseas call center - I went back to the answer you gave a few weeks ago - it worked just as you wrote.
I chatted on two occassioms to get a user friendly Channel guide. Was promised one in the mail both times and never got it. I've given up and am spending a couple days converting the internet available guide to alphabetic order so I don't have to pour over page upon page to find the # for the Channel I'm looking for
