Mac Mini with M1 Chip

HP Supported this printer up through macOS 10.12 (Sierra). Those drivers may have supported it through Mojave (10.14), but not afterward with the 64-bit only requirements of Catalina and Big Sur.

It is not supported by Apple's built-in AirPrint drivers. It might be supported by the HP Printer Drivers v5.1 for macOS (Update: 12/2020) download as it shows the Color LaserJet CP1510 series support in it. After you install this, your device will not see the driver until you re-add the printer (reset the print system…) with the CP1510 series driver.

GutenPrint for macOS (v5.3.3) shows explicit (experimental) support for the Color LaserJet CP1515n, but it is unclear how well this will install and work in macOS Big Sur with a two-year-old GutenPrint build.

See if this link helps.

In the UK it could be a fortnight.

The issue is not the Mac M1 mini, it is a combination of printer vendors disengaging support long before the devices are dead, and your not performing due diligence with HP driver support on Big Sur — prior to the M1 mini purchase. If the HP Printer Drivers v5.1 installation provides the driver support you require for the CP1515n, then all should be good.

Did you look on the HP site?

If it is airprint compatible, you can use the airprint driver.
