How to use hplip with yocto

Asked by zhangying on 2019-10-23

I use the embedded Linux yocto cross-compile environment.Hplip version is 3.12.6.
My rootfs already contains cups,hplip,ghost script,foomatic, etc., which are needed to drive the printer. As I understand it, cups and hplip can be used together. I would use cups+ with its own generic PPD to drive some generic usb printers, but that didn't work for me, so I came up with hplip. Right now I can't use hplip as smoothly as cups.

Hi,

Can you please let me that how did you install hplip on Yocto since it is not supported by HPLIP.
If you are able to add the printer, please post the output of hp-check -t here.

I don't know how cups and hplip work together,I don't know what went wrong.

Thank you
