Hi David:)

Looking at yr code, idea comes to my mind ;

Making class having universal calls for common tasks
like

oPrinter.write_at(nTop , nLeft,'Hello')
oPrinter.draw_box(nTop , nLeft,nDown,nRight,nTick)
oPrinter.paint_box(nTop , nLeft,nDown,nRight, nr,ng,nb )
oPrinter.draw_picture(nTop , nLeft,nDown,nRight, cBmpFile)
etc
.

etc.

While internaly tasks could be dispatched to different methods for
different printer types ...

define class virtual_printer as custom

output_type='PostScript'

procedure open_device
.

procedure close_device
.

procedure write_at   
lparameters nTop , nLeft,cOutpuText

do case

   case this.output_type = 'PCL4' 
        this.pcl4_write_at(lparameters nTop , nLeft,cOutpuText)

   case this.output_type = 'PostScript' 
        this.postsript_write_at(lparameters nTop , nLeft,cOutpuText)

   .
   
   .

endcase



enddefine

It could be sort of 'open source', so who ever hv valid code for controling
certain printer type can contribute in making versatile class
for programatticaly writing to laser printers.


Just Idea :))
