My resin printer was powered off with resin in the vat for about 7 months. Last night I turned it on, gave it a job, and I woke up to a successful print.
My inkjet printer was powered off for 2 weeks. Last night I turned it on, gave it a job, and was instantly disappointed with a streaky, blotchy output. Running a clean cycle just made the output worse.
Why are 2D printers so terrible despite decades of development? What are some 2D printers this community has had good interactions with/would recommend?

I’ve had good experience with Brother laser printers. They don’t seem to mind being left unused for months at the time. I have a Brother color laser printer and a Brother B&W laser printer-scanner and I like them both a lot.
If you get a printer with a scanner, I recommend using the NAPS2 freeware for your scanning. It works great with a wide variety of scanners, is simple to use but highly configurable, and is a lot less of a nuisance than the proprietary scanning software that comes with most printers. Once your OS has the drivers it needs, you generally won’t need the proprietary bloatware that comes with the printer in my experience.
As for leaving resin sitting in a vat for extended periods, I don’t recommend it beyond a few days. Sure, you can get away with it like you did, but you can also develop various problems from it. The resin will separate (easily fixed by stirring) but it can also slowly leak out of the vat and make a mess (this happened to me).
I try to make a habit out of emptying my vat (through a filter back into the resin bottle) in order to inspect and/or clean the FEP semi-regularly. I also feel better about not having an open vat just sitting around to potentially get bumped and knocked around. If I am using the 3d printer heavily I don’t bother with this, but I know if it’s going to sit idle for a week or longer, I go ahead and empty & clean the vat.
I actually have a “resin mixing” gcode file that just raises and lowers the build plate a bunch while I’m warming up the shed my resin machine lives in. That mixes it up really nicely!
As for leaving resin in the vat, thank you for the advice, however I’ve been printing with this machine since 2020 and never empty the vat unless I’m changing resins or using a water washable (which I moved away from as the detail wasn’t as crisp, and it’s just as problematic as regular resin). I do run a clean cycle after a print, peel the sheet up, cure it and toss it. Never had to replace the FEP, never had any leakage issues
