*
*    MODIFICATION HISTORY
*
* 03-Mar-91 - Adrian Thoms
*	Got rid of harmless (but untidy) extra : in printserver template
*	Put printserver help back in synch with template
*	TO BE DONE: get the templates into printcap format and avoid
*	the duplication in the help messages!!!!
*
* 25-Feb-91	Adrian Thoms
*	Fixed numerous spelling errors and corrected trademark usage.
*
* 04-Oct-90 - Adrian Thoms (thoms@wessex)
*	printserver template fix: added pp field for lpr -p support
*
* 13 Nov 89	Adrian Thoms (for Daren Seymour)
*	Changed default value for uv
*	
*    07-Jan-89  David Gray (gray)
*    Modified help message for "sd", "af", and "lf" to reflect changes
*    made to the way the files are created.
*    Modified to "xs" help message, bits to set are represented in octal
*    instead of hex. Since all other references are made in octal, this
*    makes much more sense.
*
*    November 11, 1988
*    by David J. Gray
*
*    Changed default entries for la75 and ln03r     
*
*    July 13, 1988
*    by: David J. Gray
*
*    Changed the wording of some of the help messages. There were
*    problems due to references to non-existent documents.
*
*    Added the LA120 to the printers available list, and the LP29
*    to the same list.
*
*    May 21, 1988
*    by: David J. Gray
*
*    Changed some of the default values for printers so that the
*    printers will work with factory settings.
*    ie., 8bit no parity and either 4800 or 9600 baud.
*
*    December 7, 1987  (Pearl Harbor Day - 12/7/41)
*
*    By: David J. Gray
*    Modified help messages to provide more verbose explanations to 
*    hopefully provide more useful information.
*    -> better explanation on printcap parameters
*    -> short description on each printer
*    -> more detailed information on use
*
*  8-Jul-88 Dave Maxwell (EUEG)
*    Added entries/help info for new postscript capabilities:
*	ct - connection typ
*	ps - postscript/non postscript mode
*	uv - Ultrix version
*	Da - Data type
*	Dl - Device Control Module file
*	It - Input tray
*	Lf - Layup to postscript translator
*	Lu - layup Definition file
*	Ml - Message log
*	Nu - Number up
*	Or - Orientation
*	Ot - Output tray
*	Ps - Page size
*	Sd - Sheet Size default
*	Si - Sides
*	Ss - Sheet size
*	Ul - Upper page limit
*	Xf - translator dispatch program
*    
*   Added lps40 template to printer list
*    
*  20-Jul-88 Dave Maxwell (EUEG)
*	changed lps40 to printserver
*

char h_af[] =
{"\n\
The 'af' parameter is the name of the accounting file used to		\n\
keep track of the number of pages printed by each user for each		\n\
printer.  The name of the accounting file should be unique for		\n\
each printer on your system. The information stored in the		\n\
accounting file is used by the pac(8) program. Note this file		\n\
must be owned by `daemon'. It should be if it was created using		\n\
this script. The `af' parameter is not applicable for remote 		\n\
printer entries.							\n\
\n\
When the accounting file is created, intermediate directories  \n\
will be created as neccessary. \n\
"};

char h_br[] =
{"\n\
The 'br' parameter specifies the baud rate for the printer.		\n\
The baud rate is dependent upon the printer hardware.			\n\
Consult your printer hardware manual for the correct baud rate.		\n\
The 'br' parameter is only applicable for tty devices, ie. serial.      \n\
This parameter has no effect on printers connected to the console       \n\
port or to printers connected on a parallel port.		       \n\
"};

char h_cf[] =
{"\n\
The 'cf' parameter specifies the output filter for the		   \n\
cifplot data filter.						     \n\
\n\
Printer filter entries can either be an executable program	      \n\
or a single line which is interpreted by the shell.		    \n\
"};

char h_ct[] =
{"\n\
The 'ct' parameter specifies the type of connection to the printer.       \n\
Choices are dev, lat, remote, and network. 				\n\
"};

char h_df[] =
{"\n\
The 'df' parameter specifies the output filter for the TeX data 	\n\
filter (DVI format).						    \n\
\n\
Printer filter entries can either be an executable program	      \n\
or a single line which is interpreted by the shell.		    \n\
"};

char h_dn[] =
{"\n\
The 'dn' parameter specifies the name of the daemon program to		\n\
invoke each time a print request is made to the printer.  The		\n\
default daemon name is '/usr/lib/lpd', and should not be		\n\
changed.  The 'dn' parameter is available here so that the		\n\
system may support multiple line printer daemons.			\n\
"};

char h_du[] =
{"\n\
The 'du' parameter specifies the daemon UID used by the printer 	\n\
spooler programs.  The default value, (0) should not be changed.	\n\
The 'du' parameter is available here so that printer daemons,	   \n\
other than /usr/lib/lpd, may be used.				   \n\
"};

char h_fc[] =
{"\n\
The 'fc' parameter specifies which terminal flag bits to clear		\n\
when initializing the printer line.  Normally, all of the bits		\n\
should be cleared (fc=0177777 octal) before calling 'fs'.  Refer	\n\
to the discussion of 'sg_flags' in tty(4) of the Ultrix Reference	\n\
Pages, or see help message for the 'fs' parameter. \n\
"};

char h_ff[] =
{"\n\
The 'ff' parameter is the string to send as a form feed to the		\n\
printer.  The default value for this parameter is '\\f'.		\n\
"};

char h_fo[] =
{"\n\
The boolean parameter 'fo' specifies whether a form feed will		\n\
be printed when the device is first opened.  This is in addition	\n\
to the normal form feed which is printed by the driver when the		\n\
device is opened.  To suppress ALL printer induced form feeds,		\n\
use the 'sf' flag, in addition to the 'fo' flag.			\n\
"};

char h_fs[] =
{"\n\
The 'fs' parameter specifies which terminal flag bits to set		\n\
when initializing the printer line.  Normally, all of the bits		\n\
should be cleared (using fc=0177777 octal) and then 'fs' should be	\n\
used to set the specified bits.  Refer to the discussion of		\n\
'sg_flags' in tty(4) of the Ultrix Reference Pages.		\n\

The 'lf' parameter is the logfile where errors are reported.		\n\
The default logfile, if one is not specified, is '/dev/console'.	\n\
If you have more than one printer on your system, you should give 	\n\

The 'lo' parameter is the name of the lock file used by the		\n\

The 'mx' parameter specifies the maximum allowable filesize      	\n\
(in BUFSIZ blocks) printable by each user.  Specifying mx=0     	\n\
removes the filesize restriction entirely. If this parameter	    \n\
is not specified, the default value of 1000 blocks is assumed.	  \n\
The 'mx' parameter effects the size of the job on the machine	   \n\
