Summary: This article contains an example of how to send printer control codes to an HP LaserJet printer from a COBOL version 3.0, 3.0a, or 4.0 program. This program can also be used as a basis for sending control codes to other types of printers. Note that different printers usually have entirely different control codes. Please refer to your printer manual to determine the control codes necessary for different effects. Your printer manual may list the control codes in hexadecimal notation. In COBOL version 3.0, 3.0a, or 4.0 you can use the MOVE statement to place a hexadecimal literal into a COBOL data item (this cannot be done in earlier versions, which do not support hexadecimal notation). Note that the x before the number surrounded by double quotation marks denotes that the following number is a hexadecimal literal (for example, MOVE x“1B” TO PRINT-REC).
More Information: A sample program, PRINTESC.CBL, is included with Microsoft COBOL Professional Development System version 4.0. It can be found in the DEMO subdirectory of your COBOL directory. If you did not install the sample programs on your initial setup, you can use SETUP.EXE to select the “All sample programs” component, and repeat the installation process with only the new component selected. The following is a code example:

OPEN OUTPUT PRINT-FILE.
MOVE "THIS LINE IS NOT UNDERLINED" TO NAME-STREC.
WRITE PRINT-REC FROM NAME-STREC AFTER ADVANCING 2.
*This hex code underlines text for a HP LaserJet
*The hex code is Esc&dD
MOVE x"1B266444" TO UNDERLINE-REC.
WRITE PRINT-REC FROM UNDERLINE-REC.
MOVE "THIS LINE IS UNDERLINED" TO NAME-STREC.
WRITE PRINT-REC FROM NAME-STREC AFTER ADVANCING 2.
*This is the hex code that disables underlining of text.
*The hex code is Esc&d@
MOVE x"1B266440" TO UNDERLINE-REC.
WRITE PRINT-REC FROM UNDERLINE-REC.
*Esc E resets printer
MOVE x"1B45" TO RESET-REC.
WRITE PRINT-REC FROM RESET-REC.
CLOSE PRINT-FILE.
STOP RUN.
