PRB: ?/?? Output Not Using the Specified Printer Driver

ID: Q109852

The information in this article applies to:

Microsoft FoxPro for MS-DOS, versions 2.0, 2.5, 2.5a, and 2.5b

SYMPTOMS

After you have set a printer driver, ?/?? output does not use the specified printer driver.

CAUSE

When you are printing with ?/??, the PDDOCST and PDDOCEND procedures in the GENPD.APP program are not called automatically; they must be called manually.

RESOLUTION

To avoid this problem, make sure you manually call the PDDOCST and PDDOCEND procedures. For example, the following code corrects the example shown below in the "More Information" section:

   SET PDSETUP TO "Condensed"
   SET PRINTER TO LPT1
   SET PRINTER ON
   SET LIBRARY TO LOCFILE("driver2.plb")
   ? PDDOCST(_PLENGTH,128)  && substitute 128 with desired page width
   ? "This is a test"
   ? PDDOCEND()
   SET PRINTER OFF
   SET PRINTER TO

MORE INFORMATION

Steps to Reproduce Behavior

1. Create a printer driver called "Condensed" that prints 16.7 characters

   per inch (cpi).

2. Execute the following code:

      SET PDSETUP TO "Condensed"
      SET PRINTER TO LPT1
      SET PRINTER ON
      ? "This is a test"
      SET PRINTER OFF
      SET PRINTER TO

The text "This is a test" does not print in condensed print.
