The following PERL script was written to print multiple pages in landscape
mode on a Hewlett-Packard Laserjet Series printer (PCL-lang only).
I conducted a search for other programs which would do this, but the search
was fruitless.  I hope the general community finds this program useful.

To use this program, you must install it in your printcap file.  I put mine
in the "cf" entry, for example, in my BSD-based system:

lp|local line printer:\
    :lp=/dev/lpa0:sd=/var/spool/lpd:lf=/var/log/lpd-errs:sh:\
    :if=/usr/foreign/bin/if_ljet3:\
    :cf=/usr/foreign/bin/sqprint:

The cf entry stands for "cif filter", or something like that.  Since I don't
have cif on my machine, I used the empty printcap slot for my filter.
However, if you install sqprint as a filter on your machine, be warned that
users who attempt to print cif files, or whatever filter you used, will have
quite a surprise in store for them.

To print on my system, I use:
    lpr -c inputfilename

The "-c" tells lpd to print the file using the cif output filter.

Unfortunately, very few useful arguments (such as input filename, etc) are
passed to any filters except "if" or "of", both of which you will probably
not want to override.  If you do override the "if" or "of" filters, you will
have to change the print_footer routine at the end of the file.

There is no guarantee of support from me, although I will probably continue
to add features as I find them useful.  I never intend to make a MS-DOS port.

I will not answer any mail regarding "how to install this program" or
"the program won't work with my HP calculator, what is wrong?".  If you have
problems, you will have to resolve them yourself.

Check you printcap and lpr manpages for more info.
