when i print the music, all the noteheads, rests, & accidentals appear one space (one major step) up.
for stems up parts, you can see a little of the bottom part of stem sticking out;
and for stems down parts, the noteheads and stems don't even connect
half rests look like full rests and vice-versa

i have tried printing TT fonts as bitmap soft fonts and as graphics

for now, i transposed from Gb major to Bbmajor and hand-wrote in the extra accidentals and key signature
so although the file is in Bb, it printed out looking like Gb

what's the actual solution?

thanks!
