                                                                EXHIBIT 5.1


  December 8, 1999



  Impreso.com, Inc.

  Coppell, TX 75019

  Gentlemen and Ladies:

  You have  requested my opinion,  as counsel to  Impreso.com,  Inc., a Delaware
  corporation (the "Company"),  in connection with the Registration Statement on
  Form S-4 (the "Registration  Statement") under the Securities Act of 1933 (the
  "Act"),  filed by the Company with the Securities and Exchange Commission (the
  "Commission").

  The Registration Statement relates to the offering by the company of 5,292,780
  shares of the Company's  common  stock,  $.01 par value per share (the "Common
  Stock").

  In  the  preparation  of my  opinion,  I  have  examined  the  Certificate  of
  Incorporation of the Company and the By-laws of the Company,  in effect on the
  date hereof,  minutes of meetings of the  Company's  Board of  Directors,  the
  Registration Statement and the Merger Agreement, dated as of December 1, 1999,
  among  TST/Impreso,  Inc.,  TST Merger  Corp.,  and the Company  (the  "Merger
  Agreement").  In my  examinations,  I  have  assumed  the  genuineness  of all
  signatures,  the  authenticity of all documents  submitted to me as originals,
  the conformity to the originals of all documents submitted to me as certified,
  photostatic or conformed copies,  and the authenticity of the originals of all
  such latter documents.

  Based upon such  examination,  I am of the opinion that shares of Common Stock
  covered  by and  included  in the  Registration  Statement  have been duly and
  validly authorized and, when issued and delivered in accordance with the terms
  of  the   Merger   Agreement,   will  be  validly   issued,   fully  paid  and
  non-assessable.

  I hereby consent to the filing of my opinion as an exhibit to the Registration
  Statement and to the reference to me under the caption "Legal  Matters" in the
  prospectus included in the Registration Statement. In so doing, I do not admit
  that I am in the category of persons whose consent is required under Section 7
  of  the  Act or the  rules  and  regulations  of  the  Commission  promulgated
  thereunder.


  I am inside  General  Counsel to the  Company  and own 5,250  shares of Common
  Stock.


                                         Sincerely,


                                         /s/ TAMMY YAHIEL
                                         ------------------------
