Resetting Control Characters
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.
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.
You can 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,
you must first 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 you can send in a packet
or embed in your 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 can result in an error.
Example ^CB
Immediately cancels the batch currently printing unless an error exists on the printer. This
example assumes that the defined immediate command control character is the caret (^).
The table represents the defined immediate command control character as ^ and the defined
status polling control character as d. You may define these characters to suit your needs.
