4L.EXE
======

This file is a program to display and optionally set default parameter values
in the HP LaserJet 4L printer.

	Usage: 4L [/ILT] [@filename] [parameter=value]

If 4L.EXE is executed with no arguments, the current state of all parameters
is displayed.

The following options may be specified on the command line:

	/I	Initialize Printer Defaults
	/L	Print Typeface/Symbol Set List
	/T	Print Self Test Page

Any parameter=value assignments may be specified on the command line or in a
command file (@filename).  Assignments made on the command line must be
separated by spaces, but may not contain any embedded spaces.  Assignments
made in a command file must be one per line.  See PC8-COUR for an example of
a command file.

The following printer parameters may be used on the command line or in a
command file (assignments shown are printer defaults):

	AUTOCONT=OFF (OFF/ON)
	COPIES=1 (1-999)
	DENSITY=3 (1-5)
	ECONOMODE=OFF (OFF/ON)
	FONTNUMBER=0 (0-25)
	FORMLINES=60 (5-128)
	IMAGEADAPT=AUTO (OFF/AUTO/ON)
	MANUALFEED=OFF (OFF/ON)
	ORIENTATION=PORTRAIT (PORTRAIT/LANDSCAPE)
	PAGEPROTECT=AUTO (OFF/ON/AUTO)
	PAPER=LETTER (LETTER/LEGAL/A4/EXECUTIVE/COM10/MONARCH/DL/C5/B5)
	PITCH=10.0 (0.44-99.99)
	PTSIZE=12.0 (4.0-999.75)
	RET=MEDIUM (OFF/LIGHT/MEDIUM/DARK)
	SYMSET=ROMAN8 (ROMAN8,ISOL1,ISOL2,ISOL5,PC8,PC8DN,PC850,PC852,
                       PC8TK,WINL1,WINL2,WINL5,DESKTOP,PSTEXT,VNINTL,
                       VNUS,MSPUBL,MATH8,PSMATH,VNMATH,PIFONT,LEGAL,ISO4,
                       ISO6,ISO11,ISO15,ISO17,ISO21,ISO60,ISO69,WIN30)

Examples:

	4L
	{displays the current state of all parameters}

	4L COPIES=1
	{sets number of copies to 1}

	4L PAPER=LEGAL ORIENTATION=LANDSCAPE FONTNUMBER=7 SYMSET=PC8
	{sets paper size to legal, orientation to landscape,
	 typeface to CG Times, and symbol set to PC-8}

	4L @PC8-COUR
	{uses the file PC8-COUR to make parameter=value assignments}

	4L /I SYMSET=PC8
	{initializes printer to factory defaults,
	 then changes symbol set to PC-8}

	4L @PC8-COUR COPIES=2
	{uses the file PC8-COUR to make parameter=value assignments,
	 and set number of copies to 2}

	4L /T
	{prints self test page}

	4L /?
	{displays help screen}

FONTNUMBER assignments and SYMSET descriptions are available by printing the
Typeface/Symbol Set List (4L /L).

If 4L.EXE is renamed, 4L.PRN and 4L.CFG must be renamed also (i.e.
4LCTRL.EXE, 4LCTRL.PRN, and 4LCTRL.CFG).

4L.CFG
======

This file is required only if your printer is attached to a port other than
LPT1.  If your printer is on port LPT2 or LPT3, 4L.CFG must be present and
edited to reflect the appropriate port.  If 4L.CFG is used, it must contain
one (and only one) of the following lines:

	PORT = LPT1
	PORT = LPT2
	PORT = LPT3

4L.PRN
======

This file is printed whenever 4L is invoked with the /L option.  A sample of
each internal font is shown along with its FONTNUMBER.  Also shown is a list
of each internal SYMSET value supported along with its description.

ECONO.EXE
=========

This file is a program to display and optionally set the default EconoMode
parameter value in the HP LaserJet 4L printer.

	Usage: ECONO [OFF | ON]

If ECONO.EXE is executed with no argument, the current state of the EconoMode
parameter is displayed.

Examples:

	ECONO
	{displays the current state of EconoMode}

	ECONO ON
	{turns EconoMode on}

	ECONO OFF
	{turns EconoMode off}

If ECONO.EXE is renamed, ECONO.CFG must be renamed also (i.e. EM.EXE, EM.CFG).

ECONO.CFG
=========

This file is required only if your printer is attached to a port other than
LPT1.  If your printer is on port LPT2 or LPT3, ECONO.CFG must be present and
edited to reflect the appropriate port.  If ECONO.CFG is used, it must
contain one (and only one) of the following lines:

	PORT = LPT1
	PORT = LPT2
	PORT = LPT3
