It depends on what college you are in.
If it is KU (I know it better since i was there) you can get this Epson or Canon (4 in 1) printer-photocopier-Scanner-Fax for 15-20K and get a jamaa to run it during the day/night. I say Epson since they are good machines and you will only need to change the cartridge. Position it at Nyayo or Eastern or Ngong/Kilimabongo Common rooms and you are in business.
In Universities no royalties are paid to anybody and you can even print an entire textbook. You just forget the ethics bit.
