Freezing Issue caused by network printers

V5 Issue
1

My main issue with Samba POS is that it freezes when it can not find the network printers. If your Samba POS v5 is moving slow or is Freezing this can be a sign that 1 of your network printer is malfunctioning or disconnect.

I have a setup with 2 POS and 8 network printers. Samba POS freeze and sometimes crashes if it is unable to reach a printer.

How can I fix this?

This is not the case with SambaPOS. It should not do that at all unless you try to use the printer. THis could be something with your computer.

Did you setup some kind of customization that needs access to a printer? by default this would not affect sambapos.

Interesting that you have this problem. IF you can provide more context into what is happening maybe we can help you understand it. We have hundreds of thousands of sambapos installations and we do not see cases where a networked printer would stop sambapos from working. SambaPOS only accesses that if it sends a print job.

Hi Jesse, thank you for your response. I must apologize for any misinformation. However, this happens when we send to print a ticket.

Eg: Samba Pos will crash or Freeze if the kitchen network printer is offline when the cashier submits a ticket.

Another example: if the customer reciept printer is offline then SambaPOS will freeze.

Hope this helps to explain my point better.

That helps. So this must be an issue with your printer template then. Can you share that template? Even sending a print to an offline printer will not freeze sambapos it will just popup a single error.
