@kiwa depending on the thermal printer, it may be saved on a Chinese server somewhere. The drivers send everything to the server and then prints from the server. I had a thermal printer that did that so I stopped using it.
@MxVerda@kiwa not that I know of. I didn't know until I had to install the drivers and then do a full signup process for an account. For that printer I left my only one-star review to warn people.
