Brother HL-L2340DW

Model: HL-L2340DW

Printer WebUI is http://192.168.50.40/general/status.html MAC is 2c:33:7a:12:ba:c6

gifted from The Bikery (via Jess)

drivers: https://support.brother.com/g/b/downloadtop.aspx?c=us&lang=en&prod=hll2340dw_us_eu_as

`brlaser` on linux seems to work too

Unsupported format "text/plain" -> install cups-filters

THE "MANUAL" IS AT https://support.brother.com/g/s/id/htmldoc/printer/cv_hll2300d/use/manual/index.html#GUID-CF52D2C7-FC76-4D85-94CD-21CAF1981773_159

the printer's 1line UI is surprisingly robust. use the arrows and the OK/back keys

to configure the cups network printer the URL lpd://192.168.50.40/ or ipp://192.168.50.40/ works (with the proper brlaser drivers and stuff installed)

Firmware updates

Brother only provides a windows and mac (and mobile) client to upload firmware: https://support.brother.com/g/b/faqend.aspx?c=us&lang=en&prod=hll2340dw_us_eu_as&faqid=faq00100468_001#UpdateFirmware

But I've found https://github.com/sedrubal/brother_printer_fwupd which seems to be promising
