I bought the Polaroid Hi-Print 2nd Gen to print photos for my bullet journal and to give to friends/family. The printer itself doesn’t come with a cartridge included (I got mine from Fantasy Toys), so I had to order paper separately. I ended up buying the 60-photo pack on Amazon for $44. I later found out that Xcite (online) sells the 20-photo pack for 6 KWD. Still, I preferred the Amazon option since it gave me more than double the prints at a better price compared to Xcite. Just something to keep in mind if you get the Polaroid Hi-Print 2nd Gen be surprised like I was jaja.
They don't stick much though. Source: I have the usb-c model of this hi-print printer. Apart from that, very fun to use.
I have the canon selphy 1500 and that is 6x4 photos and the quality is excellent. I recently bought the Polaroid hi print gen2 for portability and I really like it so far. Quality is not as good as the selphy but it's more good enough for my little travel/personal journal. I didn't buy the selphy qx20 as the hi print was on sale near me and about $100 cheaper. Otherwise I'd probably would have went with the qx20. I plan on taking the hi print with me to Korea in 2 weeks time so I can journal during my down time.
The hi print cartridges and the retro cartridges are interchangeable. I have the retro cartridges but have not used them yet. Yes, the sticky back aren't that good on the hi print cartridges but I don't mind as I prefer to use glue tape. For the small form factor of these printers, I am not expecting amazing quality. For me, the hi print is good for the portable size and what I am using it for. I think just give one a go, they're fun regardless.
I have a CP1500 and the Polaroid hi print gen 2. CP1500 paper is cheaper, crisper, and I like the app better than the Polaroid. I only use this at home and great for when I wanna print a good amount. The Polaroid hi print sticky paper is weak and will curl up. So, I will still use glue tape with the prints. The Kodak cartridges are cheaper, don't have a sticky back, thicker, and interchangeable with Polaroid printer. So I use the Kodak paper cartridges with the Polaroid. The Polaroid is way more portable and about the size of a standard phone, and about 1.5-2cm thick. The prints are not as crispy as the CP1500 but still really good for its small form factor. I got the hi print over the qx20 because it was about $100 cheaper and available locally to buy in store. Otherwise, I'd probably would have gotten the qx20 for the 2 print sizes.
i have the polaroid hi-print which i love! it uses the same mechanism as a traditional color printer (the yellow, red, cyan thing, so it’s not zink) so it comes out looking like you’d expect a photo to come out, and it’s on sticker backed paper. but i think it might be on the more expensive side compared to zink printers.

Canon ivy is nice, been using mine for so long. really nice to not have to use any ink or anything, paper isn't too expensive. Medium quality print, the pictures do seem to wash out over time when exposed. (husband has had a picture of our cat stuck on his iPad cover for years and it's faded a turned a bit blue, haha) I also have a Polaroid hi-print (2x3 inch photos), print quality I would say is great + also doesn't need ink, but the cartridges it uses are quite large and it feels a bit bad to use and have to dispose of a big ole piece of plastic like that. not sure on the longevity of the prints yet, haven't had it too long.
