SPL PDF Library by Initials for Squeak Code says: Write PDF files directly from within Squeak using the PDF Library Initials for Squeak Code reported on 27 April 2003 that:
I have ported the SPDF Library from VisualWorks to Squeak. It allows to
generate PDF files without the need of external tools.
The latest version has support for text, lines and TIFF images. The
library was developed and extended at SPL WorldGroup for specific
projects, and does what was needed for those projects. It is expected
that the library will continue to be extended over time as feedback is
received from the people using it.
