All laser printers use toner instead of ink to print. If you are able to scratch away the toner on your label sheet, it probably means the toner did not fuse properly onto the sheet.
In most cases, this problem can be solved by changing your printer property settings. To change your printer property settings you will need to view your “Printer Properties” and locate what paper type is selected in the “Media Type” section of your printer properties. The default setting will commonly be “Plain Paper” or “Unspecified”. We suggest selecting “Labels” or “Card Stock”. By changing this setting, you will increase the temperature at which the printer fuses the toner to the sheet. Changing these settings should help you avoid smudging, scratching, or smearing of the toner on the sheet.
