The cost of printing a hardcover book can vary depending on a number of factors, including:

1. Page count: The more pages a book has, the more expensive it will be to print.

2. Size: Larger books require more paper and materials, which can drive up the cost.

3. Color or black and white printing: Color printing is generally more expensive than black and white.

4. Paper quality: Higher quality paper will be more expensive than lower quality paper.

5. Quantity: The more copies you print, the lower the cost per unit will be.
