The structure of Press.bits is the following:

First Page(s):
	# page descriptions  // 16 bits
	# words for each page description  // one 16-bit word
	PrinterMode  // portrait=3, Landscape = 8
	PressPasswd
	-- one PageG structure for each page --
	ICCtot
	# font loads
	-- one FI structure for each font load --
Succeeding pages:
	Bits for each page image, on 1024-word boundaries.

N.B.: For printers that don't have an Orbit, the ICCtot and # font loads should be set to zero.

structure PageG :		//Page Goodie block
 [
   FirstBand	word		//Lowest used band
   LastBand	word		//Highest used band
   BitMargin	word		//Margin and
   BitWc	word		//Word count of scan lines
   BandPos	word 2	//File position of band stuff
   BitPage	word		//File position of bits (units = 1024 words)
   CopyCrucial	bit	//True if different version needed for different copies.
   SimplePage	bit
   ColorPass		bit 2	//for color printers: 0=magenta,1=yellow,2=cyan,3=black
   ColorUsed		bit	//True if color used (only scan convert once for black)
   blank	bit 11
   PageNumber word	//From original Press file.

   //*** added for Spruce-like operation
   nRecords	word
   fontLoad	word
 ]//11 words.

Fields that can always be set to zero without harm are:
	FirstBand
	LastBand
	BandPos
	CopyCrucial
	SimplePage
	nRecords
	fontLoad
