For completeness, here is an analysis of Jim's sample initialisation file:
PCL Simple <Esc>E Printer Reset PCL Parameterised <Esc>&l2a Page Size: Letter 0o Orientation: Portrait 6d Line Spacing (6 lines-per-inch) 0e Top Margin (0 lines) 66F Text Length (66 lines) PCL Parameterised <Esc>*p0x Cursor Position Horizontal (0 PCL units) 0Y Cursor Position Vertical (0 PCL units) PCL Parameterised <Esc>*c7920x Picture Frame Size Width (7920 decipoints) 7920y Picture Frame Size Height (7920 decipoints) 0T Set Picture Frame Anchor Point PCL Parameterised <Esc>&a0R Cursor Position Vertical (row 0) PCL Parameterised <Esc>%0B Enter HP-GL/2 Mode: Pen = HP-GL/2 Comment Switch language to HP-GL/2 HP-GL/2 Command IN Initialise HP-GL/2 Command SP1 Select Pen HP-GL/2 Command IP0,11176,11176, 0 Input P1 and P2 HP-GL/2 Command SC0,6600,0,6600; Scale Comment Switch language to PCL PCL Parameterised <Esc>%0A Enter PCL Mode: Cursor = PCL PCL Control Code <LF> Line Feed
Note that:
- The 7920decipoint values for the PCLPicture Frame size equate to 11inches (the length of a Lettersize page in Portraitorientation).
- The 11176 plotter unit (0.25 millimetre) values for the HP-GL/2IP command scaling points equate to 11 inches.
- The 6600 user unit (@ 300dots-per-inch) values for the HP-GL/2 SC command X-max and Y-max equate to 11 inches.
