I have just reinstalled Bookworm.
Unfortunately, when I tru tto use synaptic I get the following error:
E: The package brscan4 needs to be reinstalled, but I can't find an
archive for it.
E: Internal error opening cache (1). Please report.
Unfortunately, Google has not been of any help.
A solution to the problem would be appreciated.
Tanks in advance.
A solution may already exist on your machine if it knows about brscan.
Brother has a deb containing their smartinstaller as a bash script,
named in my case "linux-brprinter-installer-2.2.1-1" or your can get
the latest version from brothers sites, visit with firefox.
Unpack it, run it from a cli, it asks for the model number string of
the printer or scanner, goes to brother'sown linux repo and downloads
the latest version available for that device and installs and
configures it to Just Work with cups IF you have removed cups-browsed
thereby disallowing cups from setting up the default printer driver
which cannot drive the printer in anything but waste paper mode.
Brothers own drivers support every feature the printer has, accessible
from the web interface cups serves at localhost:631. Despite the poor
publicity I've seen about factory drivers, brothers drivers for linux
work 100% here. Linux support is excellent for their products.

Thank you for your encouraging reply. I have the Brother MCF-L2710DW
Laser printer and am very pleased with it. I followed your directions
and ran:
sudo bash linux-brprinter-installer-2.2.3-1
Here are the CUPS results:
Description: MFCL2710DW
Location:
Driver: Brother MFCL2710DW for CUPS (grayscale, 2-sided printing)
Connection:
dnssd://Brother%20MFC-L2710DW%20series._ipp._tcp.local/?uuid=e3248000-80ce-11db-8000-b42200417fc9
Defaults: job-sheets=none, none media=iso_a4_210x297mm sides=one-sided
I ran "Prnt Test Page" anmd got:

Well since you specced A4 paper, did you have A4 paper in the tray? and
of course, did it work? You may need to goto locolhost:631 with your
browser and configure the options to suit your environment. Also, that
uuid is unique to that printer, so it must be correct. else you'd
collect a no such device error. An ls of /dev/serial/by-id might serve
as a checking src. klipper, the better 3d printer driver, uses that to
make sure its driving the right printer since usb has rather poor id
mechanisms. from my printers output:
root@mkspi:~# ls -l /dev/serial/by-id
total 0
lrwxrwxrwx 1 root root 13 Dec 3 01:17
usb-Klipper_rp2040_E5D94D950DCD5658-if00 -> ../../ttyACM0
the E5D9..... is a unique to that chip serial number, no other rp2040
has it. So do all the stm32 controller chips.
Unforch that is not always true, as witnessed by this machine:
gene@coyote:~/src/klipper-docs$ ls -l /dev/serial/by-id
total 0
lrwxrwxrwx 1 root root 13 Dec 7 11:39 usb-1a86_USB2.0-Serial-if00-port0
-> ../../ttyUSB1
lrwxrwxrwx 1 root root 13 Dec 7 11:39
usb-FTDI_USB_HS_SERIAL_CONVERTER_FTDHG45D-if00-port0 -> ../../ttyUSB0
where there aren't any chip serial numbers, but cups seems to have other
ways of assuring its driving the correct device as a printer. One of
those is actually driving a CM11A X10 home controller.
Probably more info than you need if the test page worked,
