 PRINTSTAT()
 Determines the status of a parallel port
------------------------------------------------------------------------------
 Syntax

     PRINTSTAT([<nPrinter>]) --> nStatus

 Argument

     <nPrinter>  Designates the printer whose status is determined.  The
     allowed values of 1 to 3 correspond to devices LPT1 to LPT3.  The
     default is LPT1(1).

 Returns

     The returned value corresponds to the status of the <nPrinter> selected
     printer.  The individual bits are defined as follows:

     Table 8-2:  Printer Bit Status
     ------------------------------------------------------------------------
     Bit     Definition
     ------------------------------------------------------------------------
     1       Time out error
     2       Not used
     3       Not used
     4       Transmission error
     5       Printer online
     6       Out of paper
     7       Printer acknowledged
     8       Printer not available
     ------------------------------------------------------------------------

 Description

     If a printer error occurs, PRINTSTAT() allows you to isolate the error
     more precisely.  PRINTSTAT() returns information about why an error
     occurs.

 Example

     In this example, the printer status is only queried when the printer is
     not ready:

     IF .NOT. PRINTREADY(1)
        nStatus  :=  PRINTSTAT(1)
        IF ISBIT(nStatus, 6)         //  Test bit 6
        ? "Paper out!"
        ENDIF
     ENDIF
