If you want to be able to print out an INC listing so the owner/seller can review it before you Activate it go to the My Listings widget on the Matrix home page.
Click on My Incomplete Listings to view all of the Incomplete listings you currently have.
Select the INC listing you want to print and click the Print button.
Select the display you want and click Print.
Note: if it does not print out correctly (sides get cut off, etc.) try using the Print to PDF functionality instead. You could also try changing the print margins in your web browser. Click here for instructions on that.
