I have the Tm-t20 ii connected to network and two Linux Cash Registers are printing to its IP using JetDirect / RAW driver.
No problem if I use only one cash register but if I use two things get weird:
if I print from the 1st cash register no problems at all: as soon as I print from the 2nd the 2nd won't print.
After a couple of minutes it will print the material I've sent to print before.
As soon as this happens the 1st stops printing.
If I print from it nothing is printed and after 2 minutes or so they switch roles.
What can it be?
What can I try to fix?
