I am sure you had this question asked before: is it possible to browse the scanned copies of the hymnals or even download them in entirety? I think all in public domain should be OK for copyright reasons.
We do not have PDFs of every hymn. We do have page scans of most public domain hymns which may be png, jpeg, or jp2 formats. If there is a PDF, it will be listed in the Media section of the text or tune summary page. To print a page scan, click on the image until you see page numbers in the corners (as opposed to hymn numbers) then find the "High Resolution" link at the bottom of the page. I do not think there is a way to get the whole hymnal except by downloading each image separately. However, Google Books and Internet Archive have complete hymnals that can be downloaded as PDFs.
