Like Hans-Georg said, d stands for duplexer, n stands for networked, w stands for wireless and f stands for fax.
Also: DO NOT duplicate them all!!!! (this would most likely mess up things badly)
only the lines starting with (and including) [hp_color_laserjet_mfp_m277dw] until (and including) the next empty line. resp. see my patch :-)
