@WenzhaoTan-Chowbus According to our documentation, this means the tablet has lost internet connection, so we can't reach the printer over the LAN. Are you seeing that, even briefly?

[WenzhaoTan-Chowbus]

When this happens, some printers print out the receipt, but some don't. What should I do?

[XinxingLi-Chowbus]

@gare-bear The frequency of such errors is relatively high(Create some StarPrinter instance frequency open and close the same printer), but sometimes it prints normally. this is printer log :

@gare-bear Hi Guillermo, it seems like we can reproduce this issue 100% for every 30-40 prints. When this happens, sometimes the printer will print, sometimes not. Please help.

[gare-bear]

@coolbeet I know you've been speaking with Joshua from our dev-support team on this issue, and he's given you a handful of suggestions. Any update?

[minusoneman]

We are experiencing the same problem with a TSP100IIILAN. We cannot reproduce it every single time, but it seems more frequent when the printer is receiving a lot of print jobs at the same time.

The error message we get is:

illegalDeviceState(message: "Network unavailable.", errorCode: networkUnavailable)

The printer usually does print out the ticket even when reporting the error, which, eventually ends up with duplicate ticket prints. Very frustrating for our customers.

StarXpend 2.5.0 Printer firmware version 2.3

Can you please share what suggestions your dev-support team gave?

[minusoneman]

@gare-bear can you please help us follow up on this issue or direct us to where we can escalate this? It's a major pain point for our customers who use Star printers, and we would like to know how we can make progress on this.

[bandit-ibayashi]

We recently released version 2.7.0, in which we improved the internal processing related the Network Unavailable determination flow. Therefore, we would like you to update your StarIO10 to version 2.7.0 and check if the issue is resolved.

We are afraid keeping you waiting.

[minusoneman]

@bandit-ibayashi appreciate the attention. We'll test the latest version and revert when we have any updates to share.
