Conference kernel::unix_printing

	I'm not sure to understand the question... if you think about
"personality module", I mean "firmware" complementary modules that
customer can buy for the la600.

	So the customer that need to select the trays on the la600's
have not acquired these modules.

	I there is some code (not to extensive) to have the tray
selection work, I can write it if I have the specs, but I think
it may be more a "printcap/filter" stuff to send the correct 
escape sequences, if the "basic" la600 accept it.

	Any input will be appreciated.

I would expect that firmware to select the printer tray options are already
built in. The best place to ask if a firmware update is required for tray
selection is in the ontime::ansi_printing note conference.

Firmware update or not you still can't select the trays from the lpr
command without a supporting print filter. Since the printer uses the DEC
ANSI printer protocol I would expect the command sequence to select the
tray would be <esc>[#!v where # is the tray number.

	Thanks for inputs.

	I am aware of the Unofficial Digital Unix printing web page,
	ftp://vorpal.zk3.dec.com/html/print.html

	It looks great, but it gives to me as many questions than
	answers.

	1 - What is the relation between DECprinter filter / PCFOF filter /
  	    and PCF files ?

	2 - What files have I to customize to implement the escape sequence
	    for selecting the tray.

	    Do I have to create one printcap entry for each tray selected,
            (with what printcap variable ?), giving a different lpr name
	    for each tray selection ?
	    In this case, what happen if I issue print commands at the same
	    time on the same printer but with different tray selected ?

	    Or, does the files mentionned in 1. help me to do this (by a
	    parameter passing mechanism ?). In this case, how
	    do I pass the parameter through lpr ?

	    Or another way ?

	    3 - Is this the same thing with Ultrix (the customer have the 
	        two kinds of OS).

	    Thanks again,

	    Eric

The PCFOF filter is an updated version of the DECprinter filter. Some
of the field names were changed, and the default directory location of the
pcf files was chaned.

Start with the la600.pcf file.

No. By editing the PCF file you can create the tray names for the printer.
The names you create can then be used by the lpr -I command.

The PCFOF fitler and the DECprinter filter for Digital UNIX got its roots
from the DECprinter filter on ULTRIX so the concepts are the same. The PCF
files for ULTRIX and Digital UNIX are not 100% compatible.

Start with getting the la600.pcf file. After `input tray default:'
add the following:

input tray front:\033[1!v
input tray middle:\033[2!v
input tray back:\033[3!v

I don't know how the escapes map to the printer but this would be a start.
The names front, middle, and back are names I created. If you don't like
the names change it. Since a version la600.pcf file is planned to be
released in a future version of Digital UNIX don't use the name la600.pcf.
If you do, when the system is updated the file will be replaced with the
one on the kit and you will lose your changes.

	Thanks for inputs.

	I have now to make trials.

	What subsets do I have to install ?? (with setld I presume ) on D.Unix 
	and Ultrix, to get the la600.pcf file.
	I found .pcf.Z files on /usr/lib/X11/fonts/misc/... (OSFMITFONT405), so
	I suppose .pcf files are somewhat generic... (is it DEC stuff ??)
 
 	If I understand well, PCSOF is an extension of the traditionnal output
	filter in Unix (the "of" field in printcap).

	Does the pcf extension stand for PrintCapFile ??

	Thanks again,

	Eric

PCF = Printer Control File

All the files for Digital UNIX are located at:

	ftp://vorpal.zk3.dec.com/html/print.html

I haven't looked at ULTRIX for some time. I expect the basic DECprinter filter
and PCF files are still in the UDTPRINT440 print subset. I no longer create
PCF files for ULTRIX. So, you will need to create it.
