MTECSDK.dll uses wininet.dll to talk to internet protocols. The MTECSDK.dll. provides functions to
convert the print request into XML format using msxml4.dll and then send it to the device using
wininet.dll . It also provides functions to convert the response from the device (XML format) to key/value
pairs.
