Pretty standard payroll clerk scam, they want you to buy check paper, print out checks at home and then mail them to various people. There are various stages to the scam and everyone involved gets stuck with a bounced paycheck and possibly legal action against them.

The person never called, they only communicated through text messages by phone or through yahoo messenger. The person claims to be an employee of Techlink (www.techlink.com) but I highly doubt that's true.
