It depends. I every month get either a crackdown (obvious) or peacekeeping (ruins score with alarming speed). There are a lot of ships, including Star God mission to sway the non-existant country in Central Asia. Every month, for two years.
Aside, there's also supply ships to replenish the 10+ enemy bases, which also ruin score. And variety of other missions. Despite being in 3 year, I lack the ability to shoot down most military ships and just have to let go.
Do I need a printer, if I built a factory?

It's start to get really really grindy. What do I wrong? I mean what can I do to improve my booty. I mean. Do I really have 5-10 raids per month to keep govs happy? And for the late game: Do I have to do more raids per month to keep things running?
I think printer is explicitly required for top-tier stuff.
I'unno, don't attack low-price targets? And they're not that low-priced, you get pretty penny from the hellerium, plastasteel and other loot, and hostages. There are also other ways to get money.
You can get away with only a few BIG operations. Assault a cruiser if you can, or do an imperial probe mission. Anything which gives you a lot of dead bodies will also give you big score.
No, there are research topics, which can alleviate the score problem, but they're more of a late-game thing, though I already have one (*Rebel Trading*).
