Processing a large number of Deferred journals / registers to PDF?

SOLVED

We have a customer (v2018 Premium) who was set up with auto-posting (imported transactions) to Deferred and left it that way for about a year.  Now they want to print the journals somehow.  Is there any way to get these journals / registers processed into Paperless PDF's, or is printing to hard copy the only option? 

(There are over 67,000 lines, so printing to a PDF printer and manually naming each file is completely impractical).
