PLOT88 uses the system print spooler for ioport= 0,1,2 or 3 to output drawings in a spool data format of "RAW".
Since PLOT88 uses API32 calls to output the drawing, no assembler routines are included in the PLOT88 libraries.
 

Default printer and print spool job title:

The default printer for the system is used to output the drawing unless the printer  to use is passed to PLOT88 with the UsePrinter88 subroutine call. 
The default job title for the drawing is listed in the print spool queue as "PLOT88 Output" unless the JobTitle88 subroutine is called. 
One or more pages can be printed under the same job title.

Note:

Because PLOT88 drawings are sent to a print spooler, the following escape values are already set:
        CALL LJ0ESC(0)
   CALL EP0ESC(0)
No page is ejected before the first drawing is printed.

The following two subroutines are called after PLOTS or INTDRV. 

Subroutine UsePrinter88

Calling Sequence:

        Call UsePrinter88( printer_name)

Parameters:
        printer_name = character string of the name of the printer to use.
                              See "Printer Settings" for a list of printers.
                              Maximum 32 characters.
Example:

        CALL UsePrinter88("HP LaserJet 4")

Note:
        This routine must be used if no default printer is defined for the system
 

Subroutine JobTitle88

Calling Sequence:

        Call JobTitle88( title)

Parameters:

        title= character string of the name of the job in the output print spool queue. Maximum 32 characters.

Example:

        CALL JobTitle88("Program MIN4C Contour")

Note:

        All drawings defined between PLOTS and CALL PLOT(0.0,0.0,999) have the same job title.
