Where can I get a local printable Xfinity channel lineup?
Comcast may have it online at https://www.xfinity.com/learn/channel-lineup or https://www.xfinity.com/support/local-channel-lineup/. From there you will see the option to "Print".
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.
