- 连续介质–此介质没有物理特性（如卷筒纸、凹口、穿孔、黑色标记）来分隔标签。标签长度由^LL命令决定
- 连续介质，可变长度–与连续介质相同，但如果打印标签的部分超出定义的标签长度，标签大小将自动扩展以包含它们。此标签长度扩展仅适用于当前标签。请注意，^MNV仍需要使用^LL命令定义初始值所有所需的标签长度
- 非连续介质–该介质具有某种类型的物理特性（如卷筒纸、凹口、穿孔、黑色标记）来分隔标签

- a=正在使用的介质接受值：N=连续介质Y=非连续介质网感应d，e W=非连续介质网感应d，e M=非连续介质标记感应a=校准期间自动检测介质类型d，f V=连续介质，可变长度g默认值：必须输入值或忽略命令
- b=黑色标记偏移量（以点为单位）。这设置了介质标记相对于文档间分离点的预期位置。如果设置为0，则介质标记预计位于分离点（即穿孔、切割点等）所有值均以点列出。除非a参数设置为M，否则将忽略此参数。如果缺少此参数，则使用默认值。接受值：-仅直接热敏打印机为80到283-600 dpi打印机为240到566-KR403打印机为75到283-所有其他打印机为120到283默认值：0
