dialog box.
If you use the EPL-N1200
printer, only printers with the
7717 or later ROM version are

12-10 Troubleshooting
What to do
Delete the unnecessary printer name.
For example,
"EPSON_TCPIP_Printers\
255.255.255.255 (EPL-N2000)"
should be "EPSON_TCPIP_Printers\
255.255.255.255".
To confirm the ROM version number,
print a status sheet and make sure the
first four numbers of the Firmware
Revision number are 7717 or higher.
See Chapter 1 for information on how
to print a status sheet. Contact your
dealer and purchase a ROM update if
necessary.
What to do
Install Service Pack 3 or higher before
monitoring Windows shared printers
under Windows NT 4.0.
