Some setbacks occurred that have since been addressed, thanks to Grant Bennet-Alder, etresoft (especially etresoft!) and interested others as documented in this Discussion: 32-bit ghostscript, required for ImageWriter and other printers using CUPS.


The first obstacle was that Catalina removed all support for 32-bit executables. However, compiling the existing ghostscript 8.71 source code results in a 64 bit executable, which (at least as of this writing) can be downloaded here:



  • This package is signed and notarized by Etresoft, Inc. who retains the sole ability to remove it at will, so it's not possible to guarantee it will be available forever. In that unfortunate event one would need to obtain his or her own developer account and codesigning ability.


The second obstacle was that the ImageWriter devices were removed at some point in Ghostscript's development. Happily, Artifex agreed to re-introduce the ImageWriter devices in the current Ghostscript release, here:



The reason they were removed to begin with appears to have been lack of interest. Installing the latest Ghostscript release isn't required unless justified for reasons beyond merely using ImageWriter printers.

Summary: macOS upgrades do not break existing ImageWriter drivers—however—Ghostscript needs to be upgraded to 64-bit. To make it work, download and install Mr. Etresoft's package, or compile gs yourself from its source. The latter option can include the latest Ghostscript version, provided those devices are not removed again.
