如果您的打印机离路由器很远
提供的网络电缆只能延伸三英尺（91.44 厘米）。因此，如果您的路由器位于商店后面而您的 POS 系统位于前面，则电缆无法进行连接。
有两种替代解决方案：
购买一条较长的网络线缆，将其从路由器连接到打印机。
如果在您的商店中使用长电缆不是理想的解决方案，那么您可以购买一个额外的路由器作为您商店中网络的一部分，从而将打印机连接到此路由器。
如果 ERROR 指示器呈红色闪烁
这是由于打印机中没有纸张而导致。打开打印机，更换纸张，然后合上盖子。此时，ERROR 指示器应会关闭，READY 指示器应会亮起。
卡纸
如果以一定角度将纸张送入收据打印机，则可能会导致卡纸。如果发生此情况，请关闭打印机，将其打开，然后再次送入纸张。
如果您尝试使收据窄于指定的 3 英寸宽度，请确保使用提供的分隔线。请勿将纸张折叠送入打印机。
自定义收据
您可以自定义基本收据布局和交易描述。

If your printer is a long distance from your router
The network cable provided only extends to three feet. So if your router sits in the back of your store and your POS system sits in the front, the cable can not reach.
There are two alternative solutions:
Purchase a longer network cable and run it from the router to the printer.
If having long cables run throughout your store isn't the ideal solution, then you can purchase an additional router to connect to as part of the network in your store.
If the ERROR indicator is blinking red
This is caused when there is no paper present in the printer. Open the printer, replace the paper, and close the lid. The ERROR indicator should turn off and the READY indicator should come on.
Paper jams
If you feed the paper into the receipt printer at an angle, then a paper jam is likely to happen. If this happens, then turn off the printer, open it up, and feed the paper in again.
If you are trying to make your receipt narrower than the specified 3 inch width, then make sure that you use the divider provided. Don't fold the paper when you feed it into the printer.
Customize receipts
You can customize both the basic receipt layout and the transaction description.
Limitations when using the Star Micronics TSP100III LAN receipt printer
Shopify POS won't work with multiple TSP100III LAN receipt printers at the same time.
