Many print shops now have high quality equipment that will give your finished product a very professional look. This could be expensive, however. This is usually the most economical way to go. Some people use a three-ring binder for their book. Adding pages is easy using this method but make certain it is a good quality binder.
Many publishing companies advertise in the genealogical periodicals.
Contact several of them for their prices and methods. I have printed family genealogies using FTM and wordperfect. Either Wordperfect or Word provide for publishing today. I have spent time with Laser Express and know that a Wordperfect document would require an additional setup fee. This direct to laser print is the cheapest way to go if printing in volume.
