Printing is a feature of Perusall, but print functionality depends on the kind of document you are trying to print:

• You can print documents uploaded by your instructor if they have turned on the setting to allow the document to be downloaded.
• Books purchased through Perusall may or may not allow printing, depending on whether the publisher of the book has allowed it. If the publisher does allow printing, you may be limited in how much and how frequently you can print from the book.

If printing is enabled for a particular document, then you will see a print button in the toolbar when the document is open.
