There are several things that could be causing this.

• Check that you have selected the correct paper size (A4 or US Letter) in both exPressit™ (layout menu) AND in your printer settings.
• For most printers, there is a ‘Settings’ or ‘Properties’ button on the printer dialogue box that appears when you click ‘Print’ in exPressit™. If you are unsure how to change your printer settings, please consult your printer manual.
• Ensure that your printer drivers are up to date. Go to you printers website and you should be able to download the corresponding driver.
• Ensure that the feeder on your printer is adjusted to fit the paper exactly. This will make the print position consistent.

If this doesn't solve the problem, it is likely that your printer needs calibrating. Because printers are mechanical devices, each different model will print in a slightly different area on the paper.

• To solve this problem, exPressit™ uses a calibration tool to nudge, or offset your designs in a particular direction so that they fit the labels.
• To calibrate, select 'Printer Calibrate' from the print menu, print a calibration sheet on a plain sheet of paper, then follow the instructions on the sheet.
• Lastly, it is good practice to use the entire bleed area around the edge of each label. This will give you some margin for error when printing your designs.
• If you are still experiencing problems you can always use the below steps to manually calculate the offset-settings.
  1 - Make a new design with only the circles drawn in the CD-Label template
  2 - Set both calibration settings to 0.0
  3 - Print the label on a blank paper
  4 - Set both calibration settings to +10.0
  5 - Print the label on a blank paper
• You can measure the distance between the edge of the paper and the printed area and compare that with a label sheet. You also can see how many millimeters the printout shifted after increasing the calibration value. Knowing this you need 1 label to test the setting, you can first print in yellow, then in green, then blue.
• Doing this you can print many times on one label. Give the ink a little time to dry before you reprint.
