Printing
For big businesses or educational organizations, investing in a large-format printer/plotter like the Canon ImagePROGRAF Pro 4000s or HP DesignJet Z9⁺44″ PostScript Printer can definitely be worth it.
However, for small businesses or home office, this is a considerable investment and not every regular printer can print in such a large format. For these situations, an online printing service or local print store might be a better option, especially when you want to save money.
FAQs

A large-format printer/plotter can print A0 papers, e.g., the Canon ImagePROGRAF Pro 4000s or the HP DesignJet Z9⁺44″ PostScript Printer.
Printing A0 paper can get very expensive, especially if you want to invest in your own printer, because that means that you have to pay the high cost of a large-format printer, needed ink or toner, and high-quality paper. If you don’t print A0 paper every day, using a printing service might be more cost-effective.
