How Industry 4.0 Is Changing CIJ and Laser Printing

Industry 4.0 is changing manufacturing. Production lines are becoming more connected, data is easier to access, and manufacturers can automate tasks that once relied heavily on manual input.

Coding and marking is part of that shift.

Continuous inkjet (CIJ) and laser printers are no longer just machines at the end of a production line printing dates, batch numbers or product codes. Connected coding equipment can provide useful production information, communicate with other systems and give teams greater visibility of what’s happening on the line.

So, what does Industry 4.0 actually mean for industrial coding?

What is Industry 4.0?

Industry 4.0 is essentially about creating smarter, more connected manufacturing environments.

Machines, software and production systems can share information rather than operating independently. Technologies such as the Industrial Internet of Things (IIoT), automation, cloud computing and real-time data help manufacturers understand what’s happening across production and respond more quickly when something changes.

For coding and marking, this can mean moving from a standalone printer to a connected part of the production line.

How is Industry 4.0 changing industrial printing?

The basic job of a coder hasn’t changed. It still needs to put the right code on the right product at the right time.

What has changed is everything around it.

A connected industrial printer can provide information about its status, communicate with other production equipment and reduce the amount of manual intervention required from operators.

Here are some of the biggest benefits.

1. See what’s happening without standing next to the printer

On a large site, checking every printer individually isn’t practical.

Remote monitoring gives production and maintenance teams greater visibility of connected printers from elsewhere on the site—or potentially from another location.

Teams can see which printers are running and identify equipment that may need attention.

For businesses operating several printers or production lines, that can make day-to-day management much simpler.

2. Spot problems earlier

Nobody wants a production line to stop because of something that could have been dealt with earlier.

Connected printers can provide alerts and operating information that help teams identify potential issues before they become bigger problems.

For example, knowing that consumables need attention gives operators the opportunity to act at a convenient time rather than discovering the issue in the middle of production.

It’s a simple benefit of Industry 4.0: better information can lead to faster action.

3. Reduce manual coding errors

Product changeovers can create opportunities for mistakes.

If operators have to manually enter dates, select messages or change product information every time production switches, there is always a risk of choosing the wrong information.

Connecting coding equipment with production systems can reduce some of that manual input.

The result can be a simpler process and a lower risk of the wrong code being printed on the wrong product.

4. Make better use of production data

Industry 4.0 creates a lot of data. The useful part is knowing what to do with it.

Connected coding equipment can give manufacturers a clearer picture of printer performance and recurring issues.

Instead of asking:

“Why does this printer keep causing problems?”

teams can use actual operating information to investigate what is happening.

That can support better maintenance decisions and help identify opportunities to improve production efficiency.

5. Make maintenance more proactive

Traditional maintenance is often reactive: something fails, then someone fixes it.

Connected equipment can support a more proactive approach.

Printer status information and alerts can help operators and maintenance teams recognise when equipment needs attention before an unexpected problem stops production.

That doesn’t mean every connected printer automatically delivers predictive maintenance. But better visibility can make it easier to move away from purely reactive maintenance.

Where do CIJ and laser printers fit?

Both continuous inkjet and laser coding systems can be part of a connected production environment.

CIJ is widely used for high-speed, non-contact coding across materials including plastic, glass, metal, film and cardboard. Its flexibility makes it suitable for production lines that need to print variable information such as dates, batch numbers and product codes.

Laser coding uses focused light to create a permanent mark on suitable materials. It doesn’t require printing ink and can produce text, graphics, barcodes and 2D codes depending on the application.

Neither technology is automatically better for Industry 4.0.

The right choice depends on the product, substrate, production speed, required code, operating environment and how the printer needs to integrate with the rest of the line.

Connected coding with Linx PrinterNet

For manufacturers using multiple coding systems, having a clear view of printer status can make a real difference.

Linx PrinterNet is a cloud-based service that provides remote access to information from compatible Linx printers.

Rather than walking around the production floor checking printers individually, authorised users can monitor their coding equipment remotely and see when attention may be required.

This can help manufacturers manage their printers more proactively and reduce unnecessary interruptions.

Industry 4.0 and the rise of 2D codes

Connected manufacturing isn’t only changing the machines on production lines. It’s also changing the codes being printed.

QR codes and Data Matrix codes can connect a physical product with digital information, supporting applications such as traceability, product identification and supply-chain data.

As manufacturers move towards richer product identification, coding equipment becomes an important link between the physical product and its digital record.

CIJ and laser technologies can both produce 2D codes in suitable applications, although code quality, substrate, print size and production speed all need to be considered.

What should you look for in a connected industrial printer?

Don’t choose a printer simply because it is described as “Industry 4.0 ready”.

Start with your actual production requirements.

Ask:

  • Can it produce the code you need on your packaging or product?
  • Can it keep up with your production line?
  • Can it communicate with your existing production systems?
  • Can operators monitor its status easily?
  • Can coding information be managed without unnecessary manual entry?
  • Does it provide useful alerts and operating information?
  • Can it support future automation requirements?

Connectivity is valuable when it solves a real production problem—not simply because more data is available.

Smarter coding for smarter production

Industry 4.0 doesn’t change the fundamental purpose of industrial coding.

Manufacturers still need clear, accurate and reliable codes.

What Industry 4.0 changes is how those printers are managed and how they interact with the wider production line.

Connected CIJ and laser systems can give manufacturers better visibility, reduce manual intervention and help teams respond to potential problems sooner.

And as manufacturing becomes increasingly automated, coding equipment will need to become part of that connected environment rather than sit outside it.
