printf "\nOS X 10.10 (Yosemite) introduced extra sandboxing.  This caused\nprinters using the foomatic-rip and ghostscript packages from\nOpenPrinting to fail. This script will amend the PPDs of\ncurrent printers that use foomatic-rip so they will work.\n"
printf "\nThe changes made will only work on some of the packages from\nOpenPrinting. It is believed that the following users of the\nfollowing packages will be able to print after applying this\npatch:\nhpijs\t\tmin12xxw\npxlmono/pxlcolor (Ricoh, Lanier, NRG and others)\nsamsung-gdi\tpnm2ppa\n"

Does anyone know how to make this run under Mojave? It chokes with the errors, "The file “yosemite_foomatic_paths.command” could not be executed because you do not have appropriate access privileges." and "To view or change access privileges, select the file in the Finder and choose File > Get Info." I already have full read/write privileges on the command script. Thanks!

I believe we must remove sandboxing for this to work: http://osxdaily.com/2015/10/05/disable-rootless-system-integrity-protection-mac-os-x/
