Introduction This chapter discusses printer output. Although Clipper handles printer errors with an error trap, it is always better to avoid them completely. As a result, error traps for printer output will not become superfluous, since errors also occur during output. You can also determine a wide variety of information, such as the number of available printers or the printer status. This chapter also describes functions that support DOS print spoolers. To implement these functions, prior to starting the respective application, you must run the DOS PRINT program to make the print spooler memory resident. Files can then be exclusively passed from a program to the spooler. However, you must first reroute your print output to a file (SET PRINTER TO <file>), before you can output it in the background. Note: Since this section is about DOS-TEXT mode programming, considered as obsolete and details skipped.
