First print command is ignored.

When I send a command to print it doesn't do anything. I have to trigger the second command to print the 2 prints. They both print at the same time.
 let escpos = Neodynamic.JSESCPOSBuilder;
            let doc = new escpos.Document();

            escpos.ESCPOSImage.load('data:image/png;base64,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')

Do I have to initiate something before the print?
