\title{H-P Laserjet Plus output from \TeX.}

HPGF is the H-P version of the \C\ program described in my other note. Note
that this version only runs on the VAX, the Sun program is a version of
Beebe's printer driver (and I think it is better than mine).


To use HPGF, you
must first issue the following commands:\begintt
$USE TEX
$HOP  :== $SYS$USERDISK2:[UHAH208.CRUDE]HPGF
$HMP  :== PRINT/QUEUE=MATHSA4  \endtt
These commands only need to be given once per login, so you can insert them
into your {\tt LOGIN.COM} file. The first command tells HPGF  where to look for
the fonts. The second defines {\tt HOP} as what VMS calls a ``foreign''
command. Then you can run the program by this command: \begintt
$HOP (qualifiers) DVI_FILE \endtt
The {\tt DVI\_FILE} must be specified. If you do not specify a directory or an
extension \C\ will look in your current default directory and assume the
default extension {\tt .DVI}.  The qualifiers are all optional; they will
not work unless {\tt HOP} is defined as above.
Note this is different from any previous definition that might be
in your {\tt LOGIN.COM} file.
The permitted qualifiers are:



/c,/f,/m,/p,/q \quad  All exactly as in the Lineprinter version of Crudetype.
(See its document).
In fact the  /r  and /s  qualifiers are also there, but I advise you not to
use them.

/e, /o \quad  Print only even (respectively, odd) numbered pages. Page numbers are
determined by the {\tt count0} parameter in the {\tt BOP} commands of the {\tt
DVI} file. In principle this would allow double sided printing. In practice
this will probably be very difficult.

/l \quad Print in Landscape mode. Note that for this to work you will have to pass
suitable {\tt hsize} and  {\tt vsize} parameters to \TeX.

Eventually you should get a message ``Output on (filename)''. The default output
file name is   (your current default directory)({\tt DVI} file name)({\tt .HPL}).
Print it by \begintt
$HMP (filename).HPL
\endtt
