Modified Print Environment 
The current printer feature settings constitute the Modified Print 
Environment. Whenever a feature setting is altered using escape 
sequences, the new setting is recorded in the Modified Print 
Environment.
The Modified Print Environment is saved during a macro call or 
overlay and restored upon its completion.
A Modified Print Environment consists of the current settings for the 
items listed in Table 3-1 and Table 3-2, with the exception of the items 
listed in Table 3-3, below.
Note Not all of the Modified Print Environment features are applicable to 
every printer. To identify variations and default settings for specific 
printers, refer to the PCL 5 Comparison Guide.
