Getting Printer Status Details - Epson EPL-5700 Reference Manual

Note:
The appropriate printer port must be selected in the Chooser to
receive the necessary information from the selected printer driver
when the EPSON Status Monitor 3 starts. If the printer port is not
correct an error will occur.
If you change the printer driver in the Chooser, while the spool file
is being printed in background printing, the output to the printer
may be disrupted.
The printer status and display of the consumables, in the status
window, can only be seen when the status is normally acquired in
the Chooser.

Getting Printer Status Details
