We’ve also had issues with SPLF2PDF. Sometimes it will work fine though but as you said, issues with the Library. We’ve used RPM for the PDF. They came out with a new version that does native PDF. Some of our clients use it and speak highly of it. Check it out at http://www.as400tcpipprinting.com/as400-to-pdf-conversion.html
Best of luck to you!
“Catapult” is a real nice tool to convert to pdf and electronically distribute the pdf to other users.
