White and Transparent background printing in gray

[DosXX]

I've been using Photoshop for years and I've never had this problem. I've used this same printer before and never had this problem.

I freshly installed photoshop on my new computer and my first print has backgrounds in gray.

I've checked every troubleshooting tip on these forums and on reddit and through google search.

I have the most updated version of photoshop as of 12/16/2022, I use a  Brother HL-L0260CDW, color laser printer. I use Windows 10. 

If I set it to "photoshop manages colors" the grey is smoother, but it's still gray
If I set it to "printer manages colores" the gray is choppy and appears in lines.

If I save it as an .png image and open it with another program and print it, the grey disappears. What setting do I have to change in this version of photoshop to fix it? Every other post that has "fixes" none of them are applicable to this current version as of 12/16/2022

I will not settle for converting to PDF and printing from there, that's infeasible for my line of work and an unnecessary extra step.

I've attached the picture I'm trying to print with a white background. It's clearly white as the .png version prints in white. I've printed over 60 lemon wedges, I'm starting to go crazy. 

Please help, this error is so weird and genuinely hurting my workflow.

Hi Dosxx,

out of curiosity, what happens when you go to view and choose the gamut warning command? (cmd+shift+y)...do you still see the white as white or grey? Also, I would try to check the color settings with CMD+SHIFT+K to make sure you are using the right color space for your job (for both monitor and printing settings).

First off, transparent equals white if you make a print on anything but a printer that prints on film (transparency). 

A PNG can have transparency which is visible in an application like Photoshop. But not all applications show transparency like this; they will show white. 

Photoshop Manages Color means you must pick an ICC output profile; what are you picking, where did it come from, was it made for this printer and paper combo?
