You need to perform the operations below the first time you establish a Bluetooth connection for Bluetooth data communication.
    • 1.Detect Bluetooth devices
    • 2.Configure pairing settings
  • 1.Detecting Bluetooth devices
  • Confirm that Bluetooth is enabled on the host PC before searching for Bluetooth devices.
  • This product will show up as "CT-S251_XX"(XX is last 2 digits of unique BD address.) when it is detected.
  • Select this product from among the detected devices.
  • Note: You can search for devices and change the names.
  • When memory switch MSW13-5 is set to "No Response," nothing is displayed by device detection.
  • You can temporarily switch this setting to device detection (detect mode) by opening the paper cover and holding down the FEED button for two seconds. Detect mode is exited when the connection between the host PC is terminated.
  • 2.Configuring pairing settings
  • Normally, selecting the printer during device detection will transition directly to pairing settings.
CAUTION
  • Some host PC configurations and models may not transition directly to pairing settings after the printer is selected during device detection.
The operation required to configure pairing settings depends on whether SSP (secure simple pairing) is enabled on the host PC.
If SSP is enabled on the host PC, pairing can be achieved without additional operations.
If SSP is disabled on the host PC, you will be prompted to input a passkey.
Input the passkey as described below.
Passkey

Installing a Driver
Drivers are included on the CD-ROM that comes with the printer.
Install the driver required by your printer.
For information about driver installation, functions, and operations, see the information provided on the CD-ROM for each driver.
Visit the site below to download the latest driver versions and information.
Precautions for Creating Applications and Practical Operations
If printing is done immediately after the paper is partially cut and torn off, the top of the next print out may be distorted.
We recommend advancing the paper one line after cutting before printing.
If you are using a serial interface that has a slow data transmission speed, streaks may appear in the printouts when you are printing graphics or gradated text, which require large amounts of data.
USB interfaces may be susceptible to the effects of electromagnetic interference from the host or environment.
If this is the case, try using a cable with ferrite cores on both ends, which are very effective at eliminating EMI.

Notes:
*If print data is very dense, the print head is hot, data transmission is slow, or some other conditions, the motor and printing may occasionally stop which causes white stripes in the printout. To print high-density data, set MSW2-3 (Spool Print) to ON to reduce striping, although this increases the time before printing starts.
For a serial interface, increase the transmission speed to prevent the motor from stopping.
