I am using Photoshop CS5 on a Mac OS X operating system. I understand that the Print to PDF capability is supposed to be built in within this OS, but for whatever reason, the printer does not appear in the drop down menu. This has always worked for me in the past to get file sizes much smaller. Any suggestions as to how I can get the Print to PDF option back? Thanks.
In Photoshop you can save your file directly as a PDF in the Photoshop File menu > Save As…
Yup. That's what I use too. File > SaveAs > Photoshop PDF (*.PDF, *.PDP)
