Notice that the "Esc" and the "&
l" are dropped from the second printer command when they
are combined.  Also, the upper-case "O" that terminated the first command becomes a lower-
case "o" parameter character when these commands are combined.
Use these three rules to combine and shorten printer commands:

The first two characters after "Esc" (the parameterized and group character) must be the 
same in all of the commands that will be combined.  In the example above, these are "&" 
and "
l".

All alphabetical characters within the combined printer command will be lower-case, 
except the final letter, which is always upper-case.  In the combined example above, "O" 
becomes "o".  The final character in the printer command must always be upper-case to 
let the printer know that the command is complete.

The printer commands are performed in the order that they are combined (from left to 
right).  Be sure to combine commands in the order that they are to be performed.
