click print worksheet - no page range suggestion or 0 to 0 means all, but any input here does not seem to work. It could be a Flash bug, but the gs infinte loop and the CUPS error log "No %%Pages: comment in header!" suggests it may not be.

There is no infinite loop in Ghostscript, it only takes a very long time for Ghostscript to render the input file. Adobe's Flash player has a bug which makes it producing huge (between 100 MB and some GB) PostScript files when printing and Ghostscript takes a lot of time to render them, especially if it needs swap space. So with a computer with a lot of memory you get printouts, but it can take several minutes or even hours, with low memory it looks like infinite or Ghostscript crashes due to lack of memory.
