We are having some issues with several zebra printers that are printers that continue to release labels as they are sent. What we are seeing is that printer will error out in the windows print queue. These jobs are sent from a unix server to a unix/samba share that hands off to the windows print queue. Windows is to manage all the print queue.

This has become an issue since our volume is now heavier.

I have taken a small sample from a larger packket capture. What do we need to do to fix this, is this a problem on the zebra printer, windows print server, unix/samba hand off?

I have also captured infromation from the windows print queue and from the zebra tool.

As far as I can tell from the MAC addresses the device sending the Zero Window is a Zebra Printer. Which means that the Printer tells the other system to pause sending further data, which means that it is not able to cope with the amount of incoming packets. So yes, this is a problem with the Zebra printer - it needs to either print faster (which usually means to replace the device with a newer one), or be upgraded with more RAM to buffer incoming print jobs.

Jasper, thank you so much for looking at it, this helped with what I thought. We will increase the speed of the printer from 2ips to 6ips and see if it can keep up.
