That's not fatal, it's just a warning that the GL engine can't find
matching GL visuals for those X11 visuals.

Either set the resolution via the "-printerargs resultion=600" option of
"xphelloworld" or edit ${XPCONFIGDIR}/C/print/attributes/document and
add a resolution entry for the HPLJ4050-PCL5 model (note that you can
only add values here which are supported by the PCL*-DDX, any
unsupported value will be dropped by the verication step in the driver).

The answer is somewhere between "yes" and "no". Development of the
current PCL driver versions in the Xorg tree has stopped a couple of
months ago in favor of waiting for the versions in HP/UX - we're hoping
that HP donates these drivers back to Xorg soon (the HP/UX drivers are
far more advanched than anything we have in the Xorg tree right now -
the HP/UX drivers are more or less perfect as they had five years of
active development and bugfixing to become mature...).
