Each of the data objects follow the same object rule of containing 
delimiting fields with structured fields describing each object.

This section describes some of the software features for IPDS 
printing.

The printer supports Replicate and Trim, which improves the 
processing of IM and IO images that contain large areas of 
shaded graphics. (IM images are resolution-dependent images 
that cannot be compressed or scaled; IO images are resolution-
independent.) 

The IOCA Replicate and Trim capability allows for faster 
transmission to the printer of AFP applications with IM images 
that have large or widespread shaded areas. It also reduces the 
storage area required on the host and on the printer.

To help diagnose problems, the system provides a trace 
mechanism. Trace files store system configuration information, 
maintain TCP/IP protocol headers, and time-stamp all records.

For detailed information on this feature, refer to the “Using utility 
commands” chapter in the Guide to Configuring and Managing 
the System.

Support for the PT2 Subset of PTOCA enables the printer to 
print overstrikes, underscores, subscripts, and superscripts 
where specified in jobs.
