So I was stumbling around the internet this morning looking for something else entirely when I found the article Working with Hawking USB and Parallel Ethernet Print Servers. I was about to close the page when I noticed that it mentioned the windows only PSAdmin tool which co-incidentally is required by my Ladox LD-3101 parallel print server. Now I had previously tried to get support (new firmware etc) for it and it turns out that Ladox is the brand of a fairly small Turkish company who imports and re badges Chinese gear, however a cursory search did not turn up the ODM of the device. I downloaded hpsutil and lo and behold.. it worked with my Ladox. I also tested it against the USB/Parallel Combo Ladox Print Server we have in the office and it worked with it also, which means that I can officially throw out the CD that came with the printserver.
