Xerox Phaser 3020 on Linux ARM64

README.md

Download and extract Linux drivers that Xerox provides https://www.support.xerox.com/en-us/content/129620 The issue is that their driver is for 32-bit ARM (armhf) and is compiled in weird way.

# enable armhf support
sudo apt install libc6:armhf libstdc++6:armhf patchelf
# patch weird elf
patchelf --set-interpreter /lib/ld-linux-armhf.so.3 uld/arm/rastertospl

# install dep
sudo apt install libcups2t64:armhf libcupsimage2t64:armhf libcupsfilters1t64:armhf

# install the driver and PPDs
# source: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=xerox-phaser-3020
sudo cp libs* /usr/lib/arm-linux-gnueabihf/
sudo cp smfpnetdiscovery /usr/lib/cups/backend/
sudo cp pstosecps rastertospl /usr/lib/cups/filter/
sudo cp -ar ../noarch/share/ppd/. /usr/share/ppd/xerox/
sudo rm -v /usr/share/ppd/xerox/*_fr.ppd

This worked for Armbian on S905W (X96-mini TV box)

Could you please test it with open-source SpliX driver, with Samsung M2020 PPD file?
https://github.com/OpenPrinting/splix/

You'll need the latest git master, not the release of splix.
If it works, I'll add Xerox 3020 PPD.

Please try this splix .deb for arm64 (Debian 12, Debian 13)
ValdikSS/splix#1

I hope it works with Samsung M2020 PPD.

It works. It has been merged into SpliX main branch.
