You can print the book with either Book Id which is Hoster's way of indexing and will be a figure like you mention where the numbers before the - are the disc number and the last two digits are a track # which can be anything from 1 to 99.

Alternately you can choose to print the Disk Id & track # , this depends how you imported the information originally.
If you imported your original disc you would have entered the original makers disc id with each import so the information should be there when printing a book. If you omitted the disc id at the time of importing then you will not be able to print this as Hoster would have entered a disc Id of it's own which would be something starting with XYZ followed by a number.
If you imported them as hard drive files again this depends if the Disc id was in the original file name or whether you added it at the time.
If you used the easy import method from the build database dialog it would probably have just used one long file name so again would not have picked out the original Disc Id.
If you ended up with the XYZxxx you will not be able to edit this without reimporting those files or disc again.

To choose printing the Book Id, Disc Id, or to leave the space blank, use the drop down arrow in the last field selection box in the "Create Song Books" dialog.
