Print a bill endpoint not printing bills

[hajo-travanto]

Can't tell if this is PHP related or a problem with the API backend behind that itself, but when i call the following endpoint with a valid ID it is not printed:

https://api.ready2order.com/v1/document/invoice/{id}/print

When i directly print the same bill while creating it the ready2order hardware device directly printed it successfully. Besides that the show as PDF worked for the same bills with this endpoint:

https://api.ready2order.com/v1/document/invoice/{id}/pdf

Any ideas?

Used the same printer_id for all tests, even tried out different ones just in case. The API response was always "Bill was added to printer queue", but that queue hat no entry for the time of attempted prints while working besides that for other API actions.

When using the print endpoint there is no documented invoice_printCount, could that be part of the issue?
