Printing put file in buffer or array to send to OnPrint, etc.

What is best to use for storing the text from a file and then to send to the printer and/or screen. A buffer and how would you declare it in the Documnet is there a buffer class or would you use an arrray eg.CArray <CPoint, CPoint> m_pFileData. What we are using is from a database to do payroll calculations on. CString would be used to TextOut for the window. Any help would be greatly appreciated.

Tanks muchly...
