The String Summary tab of the Preview Design window displays a table of all strings defined by every prop in the preview (props with device type "undetermined" are not included).
If you want a print-out of your props and channel assignments to carry with you as you wire up your display, you can use this table, copy it to the clipboard, and paste it into any spreadsheet program. In the spreadsheet you can sort and filter the data, add and remove columns, and print it out.
This is the fourth of 5 tabs on the Preview Design window. The others are:
•Channel Conflicts & Bulk Changes
The String Summary tab
The Toolbar
The drop-down box allows you to filter the list by Device Type, so you can view just the LOR devices or just the DMX devices.
You can use the copy button 
to copy the displayed information to the clipboard so that it can be pasted into a spreadsheet, where it can be sorted, filtered and printed.
The Grid
You can sort the grid by any column by clicking on the heading for that column. Clicking on a column heading once will sort it in ascending order; clicking on it again will sort in the reverse order. Particularly useful is clicking on the Device Type column heading, as this will sort first by Device Type, then by Network, then by Unit, and then by Start Circuit giving you list ordered by physical connection (which makes a good reference).
