Connecting your Printer to a Computer
Serial Communications
The printer automatically detects and switches the serial port to match common serial port cabling and signal connection configurations for DTE and DCE communications. The required cable must have a
The serial port communication settings between the printer and host (typically a PC) must match for reliable communication. The Bits per second (or Baud rate) and Flow control are the most common settings that get changed. The host (typically a Windows PC) needs to have the data Flow control changed to match the printer’s default communication method: Hardware and is noted by the Host Handshake setting DTR/Xon/Xoff for legacy printer. This combined hardware (DTR) and software (Xon/Xoff) mode may need to change depending upon the
Serial communications between the printer and the host computer can be set by:
•Autobaud synchronization
•ZPL programming ^SC command
•EPL programming Y command
•Resetting the printer to its default printer configuration.
Autobaud
Autobaud synchronization allows the printer to automatically match the communication parameters of the host computer. To autobaud:
1.Press and hold the feed button until the green status LED flashes once, twice, and then three times.
2.While the status LED flashes, send the ^XA^XZ command sequence to the printer.
3.When the printer and host are synchronized, the LED changes to solid green. (No labels will print during autobaud synchronization.)
ZPL ^SC Command
Use the Set Communications (^SC) command to change the communications settings on the printer.
1.With the host computer set at the same communications settings as the printer, send the ^SC command to change the printer to the desired settings.
2.Change the host computer settings to match the new printer settings.
Refer to the ZPL Programming Guide for more information about this command.
