May be a bug, or something I’m not doing correctly.
I have a duplex printer but I want to print out single-sided and selotape a long roll together for rehearsal / pencil annotations, but it’s not accepting the single-sided option an printing both sides.
In this case it’s a piano part from an SATB plus piano score.
The printer is a Brother MFC L2750DW
other progs such as Word bring up a print dialog, and they work fine, so I don’t think it’s the printer as such.
