DOCUPRINT IPS SYSTEM
3-8 DOCUPRINT IPS SOLUTIONS GUIDE
Sense Type and Model (STM) command
When an STM command is issued by the host, the DocuPrint IPS
printer responds that it is a Group 3 page printer. It also sends
information to PSF about the printer, for example what printer model
it is (4050 for the DocuPrint 4050 IPS, 4090 for the DocuPrint 4090
IPS, etc.). The command streams that follow after this information
may also inform PSF of any required device controls or other
information.
Obtain Printer Characteristics (OPC) command
The ‘Obtain Printer Characteristics’ command allows PSF to query
the printer about the additional features and functions which it
supports. For example, a printer may pass information back to PSF
stating that it supports a specific level of GOCA, certain device
controls, can print color, has a specific resolution, or other
information. Both the IBM Group 3 and DocuPrint IPS printers return
this same type of information to PSF. However, the information
provided by the DocuPrint IPS printers describes more features
based on the additional features offered by these printers.
