Thanks for your suggestions on repairs.
The Brother driver (DCPL2640DW) seemed to do everything right except that it
shrank the page. I was able to fix that by changing DefaultPageSize,
DefaultPageRegion, DefaultImageableArea, and DefaultPaperDimension from A4 to
Letter in /etc/cups/ppd/DCPL2640DW and restarting cups. I think I may have a
stable solution now. I have left Brother_DCP_L2640DW_USB in place but expect
not to use it.

I had a lot of printer problems too when I first install Debian, version 10 at
the time.
One day I did the following and all my printer problems were resolved :
sudo apt install printer-driver-all -y
I hope this also resolved your issues with the printer.
Please note that I am not an expert Linux guru, I am just a Linux user. So, do
your due research on my advice.

The printer is connected via USB only (not wireless). When I first connected
it, CUPS (apparently) set up a printer Brother_DCP_L2640DW_USB automatically.
A corresponding file in /etc/cups/ppd was there only when the printer was on.
Because of a font-rendering problem, I also installed the driver supplied by
Brother. Now there is a printer DCPL2640DW. It and its PPD file are always
there, even when the printer is off. Sometimes there is also a third
printer, DCPL2640DW_drx (drx being the desktop's name).
Sometimes I want to use DCPL2640DW and sometimes Brother_DCP_L2640DW_USB;
they have performed with some differences I won't go into (e.g. note default
paper sizes below). The problem is that Brother_DCP_L2640DW_USB is by
default absent. If I open a file in firefox and call print,
Brother_DCP_L2640DW_USB and its PPD file appear. If I cancel the print job,
it disappears within 10 seconds. If I try to just ask lp to use
Brother_DCP_L2640DW_USB, it may say there's no such printer.
Once I set Brother_DCP_L2640DW_USB as the default printer, but as soon as
that printer vanished, there was no default printer.
Below are some descriptions I've captured. You'll see some inconsistencies,
but I don't know which ones to correct. Can I make DCPL2640DW and
Brother_DCP_L2640DW_USB both be available full-time, with
Brother_DCP_L2640DW_USB as the default? Thanks.
