Printing Errors or Lights & Stuck Print Jobs

I received 2 cartridges with my new HP printer as part of the free cartridge deal (post purchase), but it was self generated and said I had printed 79 pages already or something like that (which I absolutely had not, I mainly scan things in), and the cartridges arrived.  The existing ones were still working, so I unsubscribed to this program as its clearly skewed and I dont want to subscribe to something that I have to deal with to get right. Ill buy my own cartridges when I need them.   So aside from this printer having all sorts of issues feeding paper (which my last Canon did constantly and ended up smashed on my rockery in my front yard)...... this one is destined for the same place.  I'm tired of buying these printers and they dont work. This one wont print unless I hard cord it to the laptop, which kind of defeats the purpose, but am grateful for it working, until it wasnt.  I have had it like 4 weeks and I already have a headache.  So it wont print. Says error E0,  I was told it needed new cartridges and stopped printing so I changed them and now the on/off button is perpetually flashing and the error msg is relative to these new cartridges which are HP genuine cartridges that HP sent me.   Im just about done and have 2 printers to return to Officeworks and want my **bleep** money back.   How hard is it to get a printer that just does what it was bought for and lasts 10 years like the last HP I had (which I ditched for a newer wifi printer that ended up on the rockery - regrets, I have a few).  Chinese rubbish.  Anyway someone please help me I urgently need this  to print off some important documents and Ive had access to it for a grand total of  like 2 weeks. 

Oh and when I try to copy something, it prints blank pages....thats before it just stopped working of course.  Over it.
