2.1 New Function

2.1.1 Canon Driver Information Assist Service (DIAS)

0008-5246
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.
Characteristics of DIAS
- Local printer can acquire the configuration information in DIAS (DLL) only.
Local printer means a printer that is "Peer to Peer" connected with Local PC via LPR/IPP/
Centronics Cable/USB and that Spooler (Print queue) appears on the Local PC.
- Shared printer needs to have DIAS (Service) installed on printer server.
The installation of DIAS (Service) must be done via Driver installer.
Shared printer means a printer whose Spooler (Print queue) appears on the printer server
(Remote PC).
- However, in some cases, DIAS (Service) needs to be installed for Local Port connection.
(See "Help" > "Troubleshoot the acquisition of configuration information".
