APPENDIX A - 7
Reloading Using the FTP Protocol from a
Command Prompt
By specifying the print server PASSWORD AS THE USERNAME
when logging on, it becomes possible to upgrade the firmware of the
print server or printer (if supported). The following example assumes
that the print server password is "cambridge"
D:\>ftp
ftp> open 220.0.250.200
Connected to 220.0.250.200.
220 FTP print service:V-1.05/Use the network
password for the ID if updating.
User (220.0.250.200:(none)): cambridge
230 User cambridge logged in.

200 Ready command OK.
ftp> hash

When you see "226 Data Transfer OK/Entering FirmWareUpdate
mode", you can be sure that the firmware file is being transferred to
the print server. If you do not see this message, the file you are
sending to the printer will either be ignored or the printer will print
garbage.
You must use the "bin" command to put the FTP client into
Binary communications mode. If you do not specify the bin
command the upgrade process will not function correctly.
