I see your interest in printing cheques in QuickBooks Online (QBO), Agomez.
Currently, the Print Cheque option isn't available to international versions of QBO. In the meantime, I recommend searching for a compatible third-party tool to assist you in doing so. To do that, go to Apps and enter an appropriate keyword in the search field.
We acknowledge the need for this feature for recordkeeping. That said, I encourage you to submit your recommendation directly to our software engineers. This way, they'll be aware of the importance of this option and might consider incorporating it in our future product upgrades.
