Laser marking systems have always had characteristics that set them apart from inkjet markers:

- more expensive to buy (typically starting at around £10,000)
- cheaper and cleaner to run since there are no consumables and no waste
- higher quality output
- faster start-up procedure
- slower process
- the chemical composition of the substrate may be changed and the marked colour sometimes cannot be controlled
- units are generally self-contained but bigger and more reliable than inkjets.

Laser marking systems usually have different power ratings (typically 10, 30, 60 or 100 watts). These determine the speed of output rather than any other capability and faster machines tend to be bigger. Before buying a machine, therefore, it is important to assess your throughput needs as well as making sure the laser will successfully and clearly mark your substrate. This will determine both the type and size of device you need.

Laser markers are now becoming more accepted and are increasingly being installed where inkjet devices might have been chosen previously. This is due to their advantages being more generally known and also because capital costs are falling and the overall cost of ownership is reduced.
