Error message under Windows XP
07/02/2002
Problem
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."
Cause
Conditions to cause this error unknown. (Occurred in evaluation
PCs in Japan.)
Parallel port driver OKIPAR appears to be failing to start.
Cause (assumed)
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.
Solution
There is a file called OKIPAR.DAT installed with the driver. It
should be edited, changing the AddServices section as
follows:
[AddServices]
StartType=3 <- Change to this.
This will change the start attribute of "OKIPAR" to "Manual" and have API start it when accessing the port.
