Apparently it's a "bug in the software of popular Delio cash printers from Novitus". The product page of the printer mentioned is:

https://www.novitus.pl/en/produkty/systemy-fiskalne/delio-pr...

It can be seen that the printer already existed in 2009 and then got something ("Polish Promotional Emblem" according to Google Translate) https://www.novitus.pl/sites/default/files/certyfikaty_tp_55...

Even if it's only one model, if the companies have only that one model of printers they won't be able to sell anything until the printers are serviced.

Effectively, having such a bug in software, even in multiple units of the same model translates to a single point of failure for the company using it.
