Hi, I'm looking for something similar to wkhtmltopdf for ARM but I do not find anything, install wkhtmltopdf but I get an error when I run it (ERROR CODE) I installed xvfb and when I run it sometimes it does it gets stuck and then he turn off the orangepi if you know why happens this i will be pending to the comments or if someone has something similar to wkhtmltopdf for arm I would appreciate it to tell me.

ERROR CODE

QXcbConnection: Could not connect to display 
Aborted

 

Not exactly sure what you mean by some of your post but "sometimes it does it gets stuck and then he turn off"

Sounds like a power issue. OPiZeros commonly 'halt' when big power/usage demands are put on the SBC.
How are you powering the OPi?

I've successfully installed both xvfb and wkhtmltopdf on an OPiZ, so...
xhtml2pdf and weasyprint might be some alternatives to look into. Depending on the unspecified language/methods you're using for wkhtmltopdf.
