(1) alignment options; by flag and escape-codes

	-vt -vc -vb -hl -hc -hr -ll -lc -lr

	ESC vt		image top
	ESC vc		image vertical centre
	ESC vb		image bottom
	ESC hl		image left
	ESC hc		image horizontal centre
	ESC hr		image right
	ESC ll		lines left
	ESC lr		lines right
	ESC lc		lines center

	default is lines-left, image-top, image-left (-vt -hl -ll)

(2) Multiple fonts per label; by escape-codes

	ESC F <n> BEL	full font name (no path)
	ESC T <n> BEL	typeface name
	ESC = <d><d>	size in points
	ESC +		next larger point size
	ESC -		next smaller point size
	ESC B		bold on
	ESC b		bold off
	ESC I		italic on
	ESC i		italic off
	ESC U		underline on
	ESC u		underline off
	ESC 0		bold, italic, underline off
	ESC 1		revert to initial typeface (from -f*)

(3) Interactive WYSIWIG GUI front-ends: mslap, xvslap, even dtslap! See (8).

(4) TrueType fonts! See (8).

(5) Accept some bitmap-formats as input: mbm, xbm
	Printed "as is", with cropping. Alignment honoured
	(in case the bitmap is smaller than the label).
	See (8).

(6) drivers to provide "fast-disconnect" function for use after failed probe

(7) proper general-purpose "stacked" signal-handling - C++ exceptions for C!

(8) ********* Proper full modularisation for extensibility **********

	Seperate programs for:
		low-level printing
		text-mode rendering of bitmap fonts
		text-mode redering of TrueType fonts
		text-mode redering of fonts from a X font server
		Motif GUI
		XView GUI
		CDE GUI
		other GUIs

	All programs will have to link with the device-drivers, because they
	all need access to the drivers "printer-model geometry" code.
