I am trying to find any information on commands for JetDirect/HP GGW Server. The only mention I've been able to find in the past 4 days of searching was at Python socket communication with HP print server. I'm currently working with HP GGW v1.0, but the JetDirect GGW v2 commands in that post seem to work as well. Any help is greatly appreciated.

Sorry for the really late reply, I hope this is useful anyways. Keep in mind, I'm not 100% sure how all these commands work but this is just from experimenting.
*Tested on a HP OfficeJet 6600 printer
*Connected to port 9220 via NetCat or Telnet
*Commands appear to be case insensitive
*Maximum command length appears to be 4

serv PRINT
250 2 PRINT

Takes # of seconds as argument and will close the connection after # seconds
skid:
Accepts 1,2,4,6,7,8,9,10,14,15,17,39,43,40,96,97,98, or 99 as an argument. Depending on the number, it will print a message, for example:
220 HP GGW server (version 1.0) ready
skid 2
250 2 PRINT
220 HP GGW server (version 1.0) ready
skid 2
250 2 PRINT
This is all I figured out so far through different methods of testing I've done over the last couple days. If you have any more questions about certain commands function, I could give you a more in-depth explanation of what I know so far.
EDIT:
After a lot more searching, I found the patent for the HP GGW protocol. This might help us better understand it

No worries, I forgot about this post. I was pen testing my printer for fun. I'll have to start up again after reading your findings. Thank you.
