Set your preferences so your grid only shows the listings you want to see (favorite channels, highlight favorite shows, 3-hour grid display, 6-hour grid display). Click on the Print icon in the top right corner of the grid. A new window will open with a PDF file of your customized grid. Click on the print icon in the PDF file and only your preferred channels will print. Based on customer feedback, the grid is set to print horizontally. Vertical printing is not available.
