This isn't quite a bug... In order to fulfill being a desktop computer replacement, printing is required. I've been using HPLIP on my 3+ quite successfully to use our wireless HP printer, but the add/remove software HPLIP doesn't support Buster (Version 3.18.12). HPLIP has now released a version that does work with Buster (3.19.8) but it won't install manually on a model 4, failing in the make despite many attempts to work around the problem. Any idea when the updated version or HPLIP will be available via the add/remove software?
