I want to print my own scrapbook paper in order to sell my paper design at the local scrapbook stores. What kind of printer do I need to use to print professionally? Would I need to have it done by the printer company or what?

This can vary a lot. Ideally, you want to buy a personal inkjet printer, as lasers tend to be VERY unforgiving of what you put into them whereas on an inkjet you can fudge around with sizes and papers.

I would invest in a hand trimmer from Staples or your local scrapbook store (Should be maybe, what, $20-$30?) and trim a whole bunch of scrapbook paper to the size you want. Then, get an inkjet printer and adjust it to your specific size. Think of it as printing an envelope, you want to print 4×6 pages, you would adjust it in your printer properties to be a 4×6 size, and voila.

I’m not sure what size you want it, but an inkjet, probably in the $100-$200 range would be your best bet for getting this done. Printing scrapbook paper professionally is a can of worms you don’t really want to open, trust me on this one. I’ve worked in a Kinkos back in the day as well as working for a trade printer now, and no one will want to touch scrapbook paper for you. It’ll be better for your ego, cost, and general knowledge to just grab a personal inkjet and experiment a bit, you’ll get better results and a nice feeling of accomplishment when it turns out the way you like. :)
