Immediate Command Functions
Class Series Programmer’s Manual 12
SOH C Stop/Cancel
This command performs the same function as pressing the STOP/CANCEL Key on the printer. This
function clears the current format from the print buffer, pauses the printer, and illuminates the
Paused/Stop Indicator. (The pause condition is terminated as described under <SOH>B.)
Syntax:
<SOH>C
Sample:
<SOH>C
Printer Response: This command will clear the print buffer, pause the printer, illuminate the
Paused/Stop Indicator and/or indicate PAUSED on the LCD or graphics
display panel, suspend printing, and wait until one of the following occurs:
• The <SOH>B command is sent to the printer; or
• The PAUSE Key is pressed.
Upon which the printer will turn the Paused/Stop Indicator ‘Off’ and/or
remove PAUSED from the LCD or graphics display panel. (If the Receive
Buffer is not full, an <XON> character will be transmitted from the printer.)
SOH D
SOH Shutdown
(Non-Display Models only)
This commands the printer to ignore Immediate Commands (^A). The SOH shutdown command is
required before loading images or fonts because some may contain data sequences that could be
interpreted as Immediate Commands. After the SOH shutdown command is sent, Immediate
Commands can be turned back on by sending a valid SOH command three times, separated by a one
second delay between each command, or by manually resetting the printer. It is good practice to
check batch quantities (<SOH>E) to verify that the SOH commands are working.
Syntax:
<SOH>D
Sample: <SOH>D
Printer Response: This printer will ignore Immediate Commands (^A) until a valid SOH
command is received three times, separated by a one second delay between
each command; or, until the printer is manually reset.
