[fabarj4]

hello everyone, I tried to use this plugin but when I enter the mmfeedpage value and print it it doesn't make a difference. my code

ThermalPrinter.printFormattedTextAndCut(
            {
              type: "bluetooth",
              id: container.activePrinter.address, // You can also use the identifier directly i. e. 00:11:22:33:44:55 (address) or name
              mmFeedPaper: 30,
              dotsFeedPaper: 30,
              // printerWidthMM: container.activeLaundry.printer_width_mm,
              text:
