Resetting Control Characters
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" | }
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
in Chapter 8 for more information.
Using Immediate Commands
Immediate commands effect printer operation as soon as the printer receives them, even if they
are included within a packet or used inside quotation marks.
Use immediate commands to change immediate command or status polling control characters,
reset the printer, or cancel and repeat batches.
Enabling Immediate Commands
When the printer is first turned on, these commands are not available. To use these commands,
send the control characters packet and define the immediate command control character. The
immediate command control character is saved when you turn off the printer. Once the immediate
command control character is defined, the immediate commands are enabled.
Sending Immediate Commands
Immediate commands consist of a three- or four-character sequence sent in a packet or
embedded in an application. Each command must be sent separately.
Syntax
control character_immediate command
The printer can accept only one immediate command at a time. Sending a command before the
previous one is completed results in an error.
Example
^CB
Immediately cancels the batch currently printing unless an error exists in the printer. This
example assumes that the defined immediate command control character is the caret (^).
