Reddit mentions of Hammermill Premium Multi-Purpose 24lb Copy Paper, 8.5 x 11, 5 Ream, 2,500 Sheets, Made in USA, Sustainably Sourced From American Family Tree Farms, 97 Bright, Acid Free, Printer Paper, 105810C

For "prints" - I'm able to make 300 that have substantial amount of white space...as in not completely full color edge-to-edge, but illustration, or lots of colored text & boxes on white background. But I find to print 2 A2 cards on a sheet with a full bleed is about 30-40 seconds or so. I haven't used a stopwatch or what not, but I usually just let the printer do it's thing, I run off and do errands like the dishes, and just come back to make sure the ink isn't streaking if it's warned me that it's low. Usually a sign the ink is low is if there's like a skip in the print, or a very thin line...or if a color like magenta is done then the print will be lacking the pink tones.

I get everything from Amazon, and currently I've found these to work great:

• Hammermill 80lb Cover (it's very velvety feeling and takes ink well, not super stiff but a good overall cardstock weight). It feeds VERY WELL through the printer.
  
  
• Accent Opaque 120lb Cover I bought 1200 sheets of this. It's VERY stiff board and really adds substantial weight to greeting cards, and takes color very well. The only downside is because it is very thick, every so often the printer won't grab the paper to feed through if you try to pre-load 5+ sheets of it. I have to do 2-3 sheets at a time for the printer to be able to grab it. There's also 100lb as well that's slightly thinner and good for cards and feeds a little better but I got the 120 because I had some weird Amazon coupon to make it much cheaper than the 100.
  
  
  I've also found great color with the other following papers:
  
  
• Hammermill 24# paper Excellent for just daily printing - I found 20# to be very thin but still doable! But love the 24# because the colors turn out nice and smooth.
  
  
• Canon Luster Photo Paper This paper is amazing for photography prints...I'm not too keen on glossy types but this makes the color feel richer and the luster texture helps to hide any small jpeg articfacting or imperfections in the file/print.

By far the best bang for my buck that I've ever purchased has been my Hammermill 24lb Multipurpose Paper. I bought it when it was further on sale, for ~$21, but the current $27-28 is still insanely cheap. You get 2500 sheets of just thick enough paper. Without too much effort, you can then print some lines or dots onto it and have some lovely looseleaf. For context, okay-quality 20lb Five-Star paper is usually ~$3.50 for 100 sheets, or just about 3.5 cents per sheet. Assuming you'd pay ~$30 for enough ink to line every one of these pages and $30 for the paper itself, you'd still be saving money with better paper and customizable printing patterns. I mostly use mine for math class, where I prefer a blank canvas, and for other light notetaking or scrap paper.

This paper is so cheap and so worth the money. I've never had any issues with feathering, bleeding or any other common issues. 10/10.
