Never Printed Shipping Labels Through Paypal - Need Advice

[wingzrow]

So up until now I've been manually printing out shipping addresses, cutting them out, and then just taping them to my packages & that was the end of it. Time consuming to say the least.

Now I'm thinking of buying up a Brother QL570 label printer & going through paypal so I don't have to wait in lines at the post office. I've never done this though, EVER.

Could anyone here give me a rundown on what's involved with all of this? Is it a good idea?

What I understand:

I assume I can just drop off my packages at the post office and won't have to wait in line anymore.

I THINK tracking numbers are free if I do this and are automatically sent to customers through eBay. This would of course help if a package gets lost, etc right?

What I need help With:

Would this save me any money, appose to just waiting in line and going through the post office every time?

I guess I need a scale of some sort to weigh all of my packages as well. Printing this labels requires a scale, so what scale do you recommend?

Also, any general info & feedback about this process would be appreciated.
