Upgrade to MacOS Big SUR

My Brothers laser printer no problem with Big SUR, but when I switch over to an Mac OS desktop in September 2017 I could not get my HP Professional Laser jet 1606dn to work and I bought a Brothers(using my 1606Hp printer for my Windows desktop) . At that time my HP photosmart Colour printer worked fine on the MAC. OS Sierra. I am getting pretty fed up with Apple. So what you are saying I should get in touch with HP. Thank you for your help

My suggestion is to get in touch with Apple and talk to them. As I said before ever since I bought an Apple Mac desktop computer, I have not been able to use my professional HP Laserjet 1606dn with my Mac. I had to buy a new printer for my new Mac, but Apple reimbursed me for the Brothers Printer. The reason they reimbursed me or deducted it from my invoice purchasing a brand new Apple Mac. Before I bought this new Mac Desktop they told me that my HP printers would work, then when the printers (although my Colour Photosmart printer 8000 series did work until they upgraded to Big Sur) My HP Laserjet did not work and I had to buy a Brother's

HL-L 2320DW (an excellent printer). At that time that printer was $129.99 Cdn plus tax. Talk to Apple, they either get a fix or tell them to pay for a new printer. I am still able to use my HP printers with my Microsoft Computer with Windows 10. I am not sure what Apple is up to, they have been making a lot of changes. They changed from Iphotos to Photos. Iphotos was so much better. I believe they are contracting those App's out . Iphotos was an Apple product. It is all about money. They contracted the photo app out as it is cheaper than that Apple controls it. Hope this helps a bit. Let me know how you made out.

Thank you.
