Paxar Monarch 9850 - Manual (Page 39)

Example { I,E,"~123~063~034~124~125~126~094" p }
Changes the parameter separator character from , to ?. The
other control characters remain unchanged. It also enables the
immediate commands by defining the ^ symbol as the command
identifier.

You can change the characters in the previous example back to
their original settings by downloading this packet:
{ I?E?"~123~044~034~124~125~126~094" p }
Notice that the parameter separator is ? in this packet. This is
the parameter separator that was set before this packet. Once
the packet is received by the printer, the new parameter separator
(a comma, in this case) is valid.
Be careful when using this feature. If you forget what the control
characters were changed to, print a test label. (The test label
lists the current control characters.) See "Printing a Test Label,"
in Chapter 8 for more information.

Immediate commands affect printer operation as soon as the
printer receives them, even if they are included within a packet or
used inside quotation marks.
You can use immediate commands to change immediate
command or status polling control characters, reset the printer, or
cancel and repeat batches.
