It is important that paging slips be readable. So, if your printer ribbon is beginning to fade, please put a fresh one in. You will save wear and tear on your colleague's eyes.
Also, please send the complete paging slip with the book. There is important information on both parts of the slip that aid in getting it to the right user and then home again. Then fold the paging slip in two, printed side out, and place in the front of book to make easy to find and read.
