I believe it downloads and you install the printer. I have not used Onyx in years but pretty sure that is when you have access to it.Where is the prnInst actually located? Is it on the disk or is it downloaded when you install the specific printer?
I think the only way I will be able to get this is from somebody who is running onyx 12 and has the same printer HP L360 as the prninst file will be installed on the pc they use. Alternative is I pay for an upgradeOk, sorry then, I've got nothing.
