Sorry, I got distracted. 

There seems to be an ioctl, legacy from the hp300 printer driver, that can
tune the parameters. I'll ask whether there is a control program for this,
or whether we should write a new one.

Actually, I'll just cross-post. "HP300ers out there: is there a control
program for the 

#define PARIOCSPARAM    _IOW('P', 0x1, struct parparam)
#define PARIOCGPARAM    _IOR('P', 0x2, struct parparam)

ioctl(), which seems to have its origin in the hp300 port?"
