I do not know how it was made so just used it. From time to time I try to get hold of the fonts in pupngo but I never really got a understanding of it...h.pcf.gz -adobe-courier-medium-o-normal--12-*-*-*-*-*-*-*
h.pcf.gz -adobe-courier-medium-r-normal--12-120-75-75-m-70-iso8859-1
h.pcf.gz -*-times-medium-i-normal-*-14-*-*-*-*-*-*-*
h.pcf.gz -*-courier-medium-r-normal-*-14-*-*-*-*-*-*-*
h.pcf.gz -*-courier-bold-r-normal-*-14-*-*-*-*-*-*-*
h.pcf.gz -*-courier-medium-o-normal-*-14-*-*-*-*-*-*-*
h.pcf.gz -*-courier-medium-r-normal-*-12-*-*-*-*-*-*-*
h.pcf.gz -*-helvetica-bold-*-*--12-*-*-*-*-*-*-*
h.pcf.gz -*-helvetica-*-12*
Try to copy all original P412 fonts in there, remove the h.pcf.gz and see whats happening. You might also need to change the content of /etc/fonts...
The pupngo2012 has the gtkfonsel program but when choosing some of the present fonts it crashes.
Thats more or less what I can come up with...
