​@JoDe if you have high volume of labels that you’re printing, you might think of adding more print agents and split your printers across different print agents. Of course you would need to check your latency between IFS server and your local server where your printers are running.

I’m working with an IFS CLoud customer and they’re printing from IFS → print agent → print spooler and there’s no delay.

Yes, it is likely that flow between the printing services and devices that are causing the issue, or that one of those services could simply be running slowly (e.g. if a heavy virus scanner is running on a server or if it is simply undersized).

As Marcel noted you could potentially add more Print Agents if there is a high volume of prints that are causing that to work too hard, possibly with one dedicated purely for a subset of label printers for example.

Another issue I’ve seen can be around the pure network latency depending on where those devices are located.  For example, if you have IFS installed locally in China, the Print Manager and Print Agent in the US, and are sending the rendered print jobs back to China to print the physical label, that can add delays.  The extent of this will depend somewhat on your network configuration/speed as well as anything that might be scanning the traffic, in addition to any server throughput issues you might be running into as noted above.

​@NickPorter , ​@Marcel.Ausan , Thank you for your replies. I'll try to look into the latency and see if anything can be optimized here. 

You can also look int the config file of the print agent. We had a default value of 180 seconds in the POLL_TIME. So sometimes, the printer just took 180 seconds longer to print. Lowering that value improved the printing speed.
