I use a Mac and teach using Lightroom for the digital platform. I require students to send me pdf contact sheets for evaluation. My PC students tell me there is no pdf button available in the print dialogue window in Lightroom's Print module. Is there a plug-in that is are missing?
No, it's just that PDF export isn't built into the OS.
Tell them to send you JPEGs or to install PDFcreator, which adds PDF as a "printer".
Thanks for the quick help. I will direct my PC students to the PDFcreator, then.
