Nodejs.... was printing but stopped printting

[AHmed Almu]

We are connecting QZ to our custom Node JS application. The application was printing with no problem but suddenly stopped printing... 

the log was saying "the specified printer couldnt be found"...

After alot of trial an error, i was able to fix the issue by "reloading the QZ App in client machine"...

how can avoid this issue... to progammatically reload the application if needed to find the printer provided. 

Thank you in advance

Due to some performance reasons, we cache some of the printer information, so there's a chance that this is a bug.

Can you please provide the logs so that we can dive a bit deeper?

Hi,

The logs show the following:

2023-07-15T12:21:23,392 [DEBUG] Found 14 printers
2023-07-15T12:21:23,392 [DEBUG] Found match: ??????
2023-07-15T12:21:23,508 [DEBUG] Message: {"call":"print","params":{"printer":{"name":"??????"},"options":

Are you sending question marks for the printer name?
