A smart or digitally controlled inkjet printer can make product coding more convenient when it offers suitable text-entry and message-setting functions. Businesses can use compatible equipment to print expiry dates, manufacturing dates, batch identifiers, and other required product information. Depending on the model, operators may be able to save frequently used messages and switch between different coding requirements. This is helpful for companies that package multiple products or update date information regularly. Before use, operators should verify that the selected message contains the correct dates and format. Proper configuration, regular testing, and routine maintenance help maintain readable prints and reduce avoidable mistakes during packaging.
