Error message under Windows XP
The following message may be displayed under Windows XP: "The parallel port driver has not been installed. Run thePrinter driver setup.exe on the setup disk to install it."
Conditions to cause this error unknown. (Occurred in evaluation
PCs in Japan.)
Parallel port driver OKIPAR appears to be failing to start.
Only when the start attribute of the legacy device LPT port driver "ParPort", from XP, is "Manual" and LPT port exists, OS detects LPT port at startup and executes ParPort using the driver start API.
In NT/2000, the start attribute of the "ParPort" is "Auto" and OS starts ParPort unconditionally.
We assume that the "OKIPAR" with auto start attribute is started before ParPort, resulting in the OKIPAR failure, when the phenomenon occurs.
There is a file called OKIPAR.DAT installed with the driver. It
should be edited, changing the AddServices section as
StartType=3 <- Change to this.
This will change the start attribute of "OKIPAR" to "Manual" and have API start it when accessing the port.
