I can't print this 6-page pdf (see URL). Instead it prints only one page with the berker logo in the top-right. Reproducible: Always
poppler (the library we use to convert the pdf to ps to send it to the printer) is failing to generate a valid ps and that's why it fails. Please open a bug upstream for poppler developers to fix it at https://bugs.freedesktop.org/ Meanwhile you can probably workaround it by using the Force rasterization in pdf options in the print dialog (though the quality may be a bit lacking)
Ok, done: https://bugs.kde.org/show_bug.cgi?id=349540
