Device Drivers in SUNOS 4.0.3

[Robert C. Montjoy]

Can anyone tell one what the difference is between a sunos 3.5 device
driver and a sunos 4.0.3 device driver. I am trying to get a IKON broad
driver to work again. The upgrade from 3.5 made it stop working. 

The driver can't seem to find the IKON broad. It fails in the vpprobe
function. 

This driver is being used to drive a versatic plotter.
