To resolve this issue, try one of the following suggestions:
 

• Change the font to one where the lines of each character are of equal thickness.
  
• If you print small characters (equivalent to 6 point font size or less):
  - Change the font style to Bold.
  - Select a larger font size.
   
• Clean the print head. (For details, see "Why do my labels have a blank horizontal line running through the text of the label?".)


• Print in the [High Resolution] mode.
  Select [High Resolution] from the [Quality] options in the printer driver.
  High resolution printing can be used when you print from a computer and have connected the AC adapter, and are using either TZe or HGe laminated tape with black ink.
  TZe-FX**1 tapes are not compatible with the [High Resolution] mode.

  If your data includes barcodes, we recommend printing with the [High Quality] mode selected from the [Quality] options in the printer driver.

  To enable the [High Quality] mode, you need to download and install the latest versions of the firmware and printer driver for your printer from the [Downloads] section of this website.
  To check your firmware version, see "How to identify the printer's firmware version."
