Let’s Print PDF is a companion app for Let’s Print Droid. (ARM, x86 CPU’s only.) These apps allow Cloud-free printing on android.
Let’s Print PDF acts as a PDF rendering engine, allowing Let’s Print Droid to generate PCL and Postscript for PDF files. (a la GhostScript.)
To actually print a PDF file, you must install and run Let’s Print Droid. By itself, Let’s Print PDF acts only as a PDF viewer.
Let’s Print Droid (LPD) combined with Let’s Print PDF is print enabling software for Android phones and Tablets.

If you have a business grade laser or print server (CUPS,LPR,SAMBA, etc) , the app will talk directly to them without any off-site conversion. No print data leaves your local network unless you choose the GCP (Google Cloud Print) option. Most other print apps ship your PDF to a cloud server to convert it to something your printer understands.
