In the past I've had a lot of problem with inkjet printers, due to lack of usage the ink gets clogged up, therefore, causing the printer to cease to work. Now I'm going to buy a new printer but instead of just going out and getting a printer that looks cool and is expensive (My current printer, which no longer works, cost me $500 [3-in-one]), I want to do some research, and this seems like a good start (apart from google, but I want some personal opinions also, as they are more valuable for me). Here are my questions

1.) Will buying a laserjet printer aid in removing the clogging problems?
2.) What are the advantages/disadvantages to a LaserJet printer in comparision to an InkJet?
3.) What printer models and/or companies (e.g. Hewlett Packard) would you recommend. Due to past experiences please do not include Canon, no matter how many times it would be recommended to me, I won't buy it.
4.) Any other opinions regarding printers you might have, I can use everything Thank You

EDIT: 5.) Which printer models provide more ink economy
