2.1.2 Canon Driver Information Assist Service (DIAS)
0008-5590
This is a subset version of the Netspot Suite Service, supporting Driver only: we have
selected Driver's functions (mainly, the functions to acquire Device configuration
information) and redesigned them.
The DIAS has the following functions:
- To acquire Device configuration information (acquisition when setting up Printer
Property.)
- To acquire calibration information (acquisition when setting up Printer Property and
printing by the color LBP, Color iR, and etc.)
- To make recognition in department-control printing (communication when setting up
Printer Property or when making a department-control print)
Main structure of DIAS
DIAS (DLL): It is a module loaded on Driver
DIAS (Service): It does a service of installation on printer server when using a shared
printer (resident process)
CBT: It is a module group to control a local port, such as Centronics Cable or USB
H-VDC: It is a module group which are needed for the driver function in DIAS.
