Continuing to use Bookworm Pup64 as my daily. Set up with my customizations on ydrv, no fdrv, no adrv, bdrv as needed, all browsers etc. as portables. Savefile used temporarily as an easy conduit to the ydrv for major changes. Other than the multimedia hiccups reported by peebee, it is running superbly in daily use.
I just got around to checking the printer installs for my Brother HL-2170W laser run using HP PCL4/5 emulation and my old HP4500 all-in-one needing HPLIP. Both ethernet connected with static IPs. Both were detected correctly with the firewall off and the Brother Install was routine. The HP install using @rcrsn51s' hplip_print_scan_bionic_64bit-3.19.8-2.pet, which had worked for me up through another jammypup64, resulted in a 'failed filter', almost certainly due to the newer ghostscrupt in Bookworm. Using HPLIP installed with the APT package manager it worked perfectly. To my surprise, the HPLIP from that install was only 437KB.
While I was at it I checked an install of PCManFM using that package manner and that also went well (My usual is pet installed or resident in a repurposed ydrv).
A suggestion for the next release. The bdrv is really essential to the release as it contains the APT package installer and is only 13MB. Why not just incorporate that in the main SFS?
