Barcode Printing

Can I use plain paper labels in a thermal label printer?

No. Thermal printers require labels with a thermally sensitive layer that prints under pressure from a printer head. Paper labels are only suitable for use with a Thermal Transfer printer which uses a printer ribbon.

Does a certain type of font need to be used for printing extended code 39?

No, a regular code 39 font can be used. Code 39 uses pairs of characters which represent single encoded ascii characters. There would be an option for this on the device you are using. The code 39 specification outlines special character pairs and asci values. These can be accessed from www.almglobal.org.

When printing code 39 formatted fonts in an Excel spreadsheet, the resulting labels won’t scan. Why is this?
There are two main reasons why this might happen. The first is that you haven’t included a * at the beginning or end which is a requirement of code 39 symbology. This can be fixed quickly using the insert function in Excel. The second is that the font you are using could be too small and these are only effective with high quality printers. Barcodes can also be ‘cut off’ within cells resulting overlaps into adjacent cells.
