Hi, Wub68!
Thanks for reaching out to Microsoft Community and posting your concerns. We're sorry to learn you encounter issues setting up your HP Color LaserJet Pro MFP M277dw printer on to your Surface Pro X due to driver compatibility issues. You're right that
is has something to do with the ARM Processor. The universal printer driver you selected is 64-bit. Please check the Surface Pro X app compatibility page to be guided accordingly.
- 64-bit (x64) apps won’t work. You'll need 64-bit (ARM64) apps, ***32-bit (ARM32)***apps, or ***32-bit (x86)***apps.
You can usually find 32-bit (x86) versions of apps, but some app developers only offer 64-bit (x64) apps.
The organization that develops the app determines whether their app will work on a Windows 10 ARM-based PC. Kindly check with HP Support if they have a version that is compatible with devices using an ARM chip or if they have plans to develop one in
the future as it is up to the printer manufacturers to make compatible drivers for Windows 10 ARM-based devices.
There's a workaround for existing HP printers though, the HP Smart app available at the Microsoft Store app may help you out. Kindly check with HP on printers that works well through the HP Smart app. Someone mentioned through this thread link about the HP Smart app.
There are some links that will lead you to non-Microsoft websites. Please watch out for ads on the sites that may advertise products frequently classified as a PUP (Potentially Unwanted Products). Thoroughly research any product advertised on the site
before you purchase it.
I happen to have seen this page from the HP Support website. Kindly check this out as it helps understand about HP Printers - Install and Use the HP Smart App (Windows 10). You may also visit this page to learn about
Mobile Printing Solutions with HP Printers.
We hope this helps you out.
Kind regards,
