OpenPCL - Open Source PCL Viewer, Converter & Toolkit. It can be used as a backend component for developers/integrators or as a standalone desktop application for end users.
Seems to accurately generate images of circuit diagrams that I could only formerly print out on a HP Laserjet 4L. The printer died, and now I can display/print my saved PCL files. All this on Fedora 17. Thank you.
good project openpcl
