ZC350 magnetic encoding without SDK

I just "upgraded" to a ZC350 printer having used an older Zebra and then an Evolis card printer with mag. encoding. Previously, it was very easy to write to Track 1 just by sending a string to the card printer enclosed by the sentinels or delimiters. Is this still possible with the ZC350? I've installed the Link-OS SDK but I don't use Java nor .Net for the Point of Sale application that I use in house.

Any suggestions?
