I would like to get data about ink, free pages (paper) etc from the printers in company network. Each of these printers (mostly Minolta) has an www interface, so I can get these data by creating browser process in my program, direct it to go to the address "http://192.168.X.YY/data.htm", download all the page code and retrieve the data from it. Is this possible without this process? If I know that these data are under each IP/data.htm can I use this information to download data in the different way: socket, ftp, etc.
In general: if you have some data on the website (no database access obviously), how you retrieve this data?
From the looks of it, your printer provides REST-based services. You can use libcurl to make REST based API calls. (This holds for most websites also!)
