SP Printer Issues

 This is how printing is handled by the library
 functions. You need not follow this method except where it is
 imbedded in SuperLib metafunctions.

 The function SLS_PRN() is a SET/RETRIEVE function
 which sets and retrieves the default printer port as a string
 with the default as "LPT1". This function may be called with any
 valid printer port name as a parameter to set a new printer port
 for SuperLib usage.

 Valid values are "LPT1", "LPT2", "LPT3", "COM1",
 "COM2" - anything you could issue a SET PRINTER TO
 <cPort> with.

 Another SET/RETRIEVE function - SLS_PRNC() - points
 to the setting which determines if the printer port will be
 checked for readiness before printing. Passing it a False causes
 it to not check the printer before printing - handy in some
 network situations.

 At print time, LPT* ports are checked for readiness
 via the P_READY() function. (COM ports are not checked for
 readiness.) However, if SLS_PRNC() has been passed a .f., no
 check for readiness is done.

 P_READY() uses the .ASM function ISPRN() to check for
 readiness.

 If the port is not ready, the user is given
 the option to:       Try Again
                      Ignore the Warning
                      Select a Different Printer Port
                      Abort the print request

 If Abort is selected, P_READY() returns false.

SP_SLS_PRNC

SLS_PRNC()

  Short:
  ------
 SLS_PRNC() A Superlib printer setting function

 Returns
 <lSetting> => Current value of the setting

 Syntax
 SLS_PRNC([lNew])

 Function                   Setting                     Default
 --------------------------------------------------------------
 SLS_PRNC([lNew])           Check printer ready         .T.
                            (set to .f. on
                            a network)
 [lNew] sets the setting to a new setting
 If [lNew] is passed, the setting is changed and the
 new setting is returned.


 Examples

  SLS_PRNC(.f.)        //  DO NOT DO A HARDWARE PRINTER READY CHECK

SP_P_READY

P_READY()

  Short:
  ------
  P_READY() Determines if printer is ready, prompts user

  Returns:
  --------
  <lReady> => True if printer is ready

  Syntax:
  -------
  P_READY([cPort])

  Description:
  ------------
  Checks for printer ready, and prompts user to ready
  the printer until it is ready, or until user presses escape to
  abort printing.

  P_READY() first looks at SLS_PRNC(), and if the
  value is .f., does no printer check and returns .t.

  [cPort] - LPT1 LPT2 LPT3
  Default is LPT1

  Examples:
  ---------
   if P_READY("LPT2")
     REPORT FORM yayaya TO PRINT
   ENDIF

  Notes:
  -------
  To stop P_READY() from checking the printer port (as
  it is imbedded in many SuperLib functions), call SLS_PRNC() with
  False. This turns printer checking off. (i.e. on a network)
