First of all, thank you so much for your response and help. I apologize for not answering before, but I was expecting to receive an email. I talked with sales people reporting I needed help and I was informed my issue has been replied.
Let me tell you that we have not been able to solve the issue. I have attached a zip file with 5 documents. File 0 is an excel file and it is the source document. File 1 is a PDF that was generated using Office Excel printed with an Amyuni virtual printer (http://www.amyuni.com), this is what we expect to achieve with Aspose. File 2,3 and 4 are all wrong. File 2 was generated wirh Aspose directly using a saved method. Here you can see that the text is truncated ("LAMINADO EN CALIENTE SIN COSTUR" instead of "LAMINADO EN CALIENTE SIN COSTURA"). Actually the text is there (the letter "A"), If you copy the text and paste it, you will see it, but in the PDF appears truncated. This is the main issue we want to solve. This portion of the excel file it is the one that is not working fine, you can see other text truncated also. File 3 is another attempt, this file was generated with Aspose (manipulation of data) and printed to PDF wit amyuni. It is wrong too. Here you can not select the text, it is just truncated also. File 4 was generated with options you mentioned in your reply. It did not work also.
Amjad, I can not tell you how important is for me to solve this issue. I really do not want to have Office suite in our windows server 2008 (we are migrating this solution from a windows 2000 that consistently crashes and I think is due to automation issues).
Now it is urgent for me to solve this problem.
I am looking forward to hear from you as soon as you are able to.
Please, I await for your reply.
