2.1 Basic Function
2.1.1 Canon Driver Information Assist Service (DIAS)
0011-3456
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 Ca-
ble/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".

About the version indication
The same Driver version indication as the one via Netspot Suite Service appears only when communicat-
ing with Device via DIAS (Service) (i.e., when connected through a shared printer).
Compatibility of DIAS and Netspot Suite Service
DIAS and Netspot Suite Service are compatible and independent. Driver supporting DIAS does not use
Netspot Suite Service even if it is installed.
Cautions when using DIAS
CBT controls all access to Local Port; both DIAS (DLL/Service) and NetSpot Suite Service use CBT to
access Local Port from the same PC.
CBT was installed only on Netspot Suite Service before; it is automatically uninstalled in response to un-
installing the existing NetSpot Suite Service. Follow the procedures below when uninstalling the former
versions of NetSpot Suite Service v3.40 and when uninstalling JobMonitor v4.20 and former.
- Reinstall DIAS after the uninstallation is complete. (Reinstallation of DIAS is enabled via Installer.)
- Update NetSpot Suite Service to the latest version (v3.40 and later).
Former versions of NetSpot Suite Service v3.40
PS Printer Driver v2.10 and former
PCL5e Printer Driver v6.11 and former
PCL5c Printer Driver v6.11 and former
PCL6 Printer Driver v6.11 and former
