Brother HL-L2340DW

NOTE: This is a MONOCHROME printer. No color. If you wanna print color stuff go to the print shop downstairs, open 10 AM to 6 PM

@@@@@ PLEASE do not leave stuff on top of the printer. it WILL jam and fuck up remote printing @@@@@

Model: HL-L2340DW

`lp -o sides=one-sided` is still printing two-sided

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

`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).

gravy: within the cups ui, use generic make, generic PCL laser type, and ipp. works on my machine

Firmware updates

Via the WebUI

Apparently the printer can be updated via the webui successfully

Remotely

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
