I found a description that recommends offering providing a page for printing. Surely I can find pages in a PDF for printing on many sites. The article says that it’s better for a long page, or series of pages to print by PDF. Drupal can provide a link to a page for printing on each Book content-type page.
I installed Printer, e-mail and PDF versions module for offering a link to a page for print not only on the Book page but other content-type pages. This module puts links to the page for printing, PDF version, and sending it by email on each content page.
Using this module, it is necessary to install an additional tool for creating PDF pages. This module supports dompdf and TCPDF, but dompdf doesn’t support Unicode, then I chose TCPDF.
Downloaded from the link below,
and install it under ‘sites/all/libraries/’. Previously it can be installed under ‘sites/all/modules/print’, but now you should install external libraries under ‘/sites/all/libraries/’.
I needed to install Japanese fonts. Referring to the page below,
I installed IPA font, it works well.
