This is now an open source drive that works on arm: brlaser, v6

Those drives (even if you use the linux ones) do not work on the raspberry pi, because it's an arm processor. You can use IPP, or install the open-source 'brlaser' driver. Support was added for HL-2270DW in brlaser 6, but debian 10 (stable raspbian) is only on brlaser 4. So you need to either upgrad...

The brother driver won't work on ARM. You can use IPP as suggested, or install the open-source 'brlaser' driver to use USB, which does work on arm. Support was added for HL-2270DW in brlaser 6, but debian 10 (stable raspbian) is only on brlaser 4. So you need to either upgrade to testing, or build f...

Use the 'brlaser' driver version 6. It's available in Raspbian 11 (currently in testing) as 'printer-driver-brlaser'. Or, if you don't feel like upgrading to 11 you can install it from source: https://github.com/pdewacht/brlaser . You'll also need to install at least some of: lpr cups ghostscript I'...

Yup, this was pure curiosity from a hobbyist messing with writing early-stage bootloaders/microkernels, about all the steps that would happen before my stage of bootloading got called. From the Debian Wiki: "All Raspberry Pi models before the 4 (1A, 1B, 1A+, 1B+, Zero, Zero W, 2, 3) boot from t...

Is a dump/source of the Raspberry Pi 4 bootloader available (the ROM, not the EEPROM)? Thanks in advance, I know this is really a developer question but I figured this board was the best fit.

If you do dump this, please make sure to note exactly which model you have.
