PCL6 Driver for Universal Print
U/I
Driver
1. The PCL6 Driver for Universal Print queries its built-in Caps DB to find out
what information should be displayed.
2. The Caps DB queries the connected device for the plug and play name and
installed options.
• Bi-directional communication required.
• SNMP required. *Only SNMP V1 and V2 are supported.
3. The Caps DB selects the PSD file based on the plug and play name and
reads the contents.
4. The Caps DB, after having read the PSD file in step 3, sends information to
the UI so an appropriate interface can be created for the model.
5. Based on model-specific data in the PSD file, the driver creates print data.
