Any reason why

lp -o sides=two-sided-long-edge 1.pdf

would only print one-sided ?

I am expecting to see one page printed on both sides, instead I am getting two sheets of paper printed on one side.

when i do

lpoptions -p Brother_HL_2270DW_series -l

I get

    I had this problem and I fixed it using using -o BRDuplex=DuplexTumble on the command line. – mikemtnbikes Dec 9 '20 at 22:22

I still don't know "why", but I fixed my issue by setting the resolution to 612 x 792 - and now the lp command to print double sided works.
