HP LaserJet + symbiont and forms library

This symbiont allows 3 different modes of printing on A4 paper:

	PORTRAIT	Portrait Courier (the default). 75 chars/line
	LANDSCAPE	Landscape Courier. 107 chars/line (up/down page)
	COMPRESSED	Portrait Compressed Lineprinter. 125 chars/line

To use a different paper size, change the forms definitions in INSTALL.COM
and in START_LASER.COM. Good luck!

To use the laser, type a command such as:

	$ PRINT /QUEUE=SYS$LASER FRED.TXT	! Will print in PORTRAIT
or	$! to print in lineprinter compressed...
	$ PRINT /QUEUE=SYS$LASER /FORM=COMPRESSED FRED.TXT
	$! etc...

Changes in this release:

1.	Placed protective ANSI DCS sequences around the form escape
	sequences.

2.	Modified START_LASER.COM to check if the terminal port is spooled
	before setting it to NOSPOOL (then back to spooled). ie. the startup
	is now much more intelligent.

3.	Two forms of the symbiont are now generated by BUILD.COM:

	PSM_LASER	Prints to HP LaserJet without any character
			translation.
	PSM_MAP_LASER	Prints to HP LaserJet with DEC Multinational Character
			set to HP character set translation.

	With PSM_MAP_LASER as the symbiont, use PRINT/FORM=DEFAULT to ensure
	that the character set used by the HP LaserJet matches the translation
	table in PSM_LASER.C.

	DEC multinational characters not mapped, or not mapped directly are:
		A9		copyright ©, mapped to "c"
		B9, B2, B3	superscript ¹²³, mapped to 1,2,3
		B5 		µ micro, mapped to "u"
		B6		¶ paragraph, not mapped
		B7		· centred dot, mapped to "."
		D7, F7		OE upper × and lower ÷ case, not mapped

Files:

PSMDEF.H
PSM_LASER.*

	Source files for modified print symbiont to prevent extra form
	feeds from the laser printer and to convert from DEC Multinational
	Character Set to HP LaserJet character set.

BUILD.COM

	Command file to generate PSM_LASER.EXE and PSM_MAP_LASER from source.

INSTALL.COM

	Command file to install PSM_LASER and PSM_MAP_LASER in
	SYS$COMMON:[SYSEXE], START_LASER.COM in	SYS$MANAGER: and to place
	LASERJETLIB.TLB in SYS$SHARE:.
	Just execute it in the current directory.

START_LASER.COM

	Command file to execute at system startup.

	P1 is the name of the print queue to generate. Default is SYS$LASER.
	P2 is the name of the serial interface to use. Must be specified.
	P3 is the name of the symbiont processor (either PSM_LASER or
		PSM_MAP_LASER) Default is PSM_LASER.
	P4 is an optional descriptive text for the queue

	eg. in SYS$MANAGER:SYSTARTUP_V5.COM, insert the line:

	$ @SYS$MANAGER:START_LASER SYS$LASER TTA2:	!

	This command file is "intelligent". It may be executed while the
	queue is running to move the queue on to another port. Look at the
	file for infomation.
