Greetings all-
I'm new to Webwork, and am the network administrator supporting some of our faculty who desire to use the program.

We are having an issue that manifests itself when a student attempts to download hardcopy for a homework set. At the Hardcopy Generator screen, the only option I have is to generate a PDF copy. When I click on the "Generate Hardcopy" button, I get this error:
