Had to fill out a pdf form today, and some of the lines weren't formified(or whatever you call it). I imported it into libreoffice draw, and filled in the blanks by hand. Worked ok, but more tedious than it should have been. Exported it to pdf. 6MB(whoops, should have compressed the photos, but not the biggest deal in the world).
Print the document, and... It has a colored background. wtf?! Dig through the settings, change a couple things that shouldn't do anything, and it still prints in color. Think about it for a bit... Could it be the colored background I use? I have it set to use a medium grey background so my eyes don't get raped by the screen. It doesn't affect spreadsheets, but... Change it to white, and everything prints ok. I guess I can see why it behaves that way on the graphics portion of the program, but it breaks consistency, and it lost me ~.5 hour of time. I might file a bug report. Gotta check extra close to make sure I'm not being a dumbass first.
