I was able to build net-print/gutenprint on my ARM64 laptop and then use it to print documents on a USB printer. Here is the list of rules I added to accept_keywords: =net-print/gutenprint-5.3.4-r2 ** Reproducible: always Steps to Reproduce: 1. Add ** keyword for net-print/gutenprint 2. emerge net-print/gutenprint 3. Start CUPS and add the new printer 4. Use the new printer Actual Results: It works! Expected Results: It works!
