Edge print agent: Slow to print

hi Folks
we are using the Kinetic edge agent for our MES printing (on premise 2022.2). But it seems to work quite slowly at times, maybe taking up to 20-30 secs before the print happens on the locally attached USB printer.
On the same PC’s non Epicor prints are instant or a print using the standard epicor client, printing works fine also

Has anyone else experienced this? any ideas on what could help improve the speed?

cheers
