Subject: [hpoj-devel] Adding HPIJS Support with HPOJ in RedHat 7.1
Date: Tue, 04 Sep 2001 08:29:35 -0400

Hi,

Attached is a prescription for adding HP InkJet driver support to RedHat
7.1. It requires some rather complicated modifications to your setup,
but since a couple of other people have followed it with reasonable
success, I thought I'd go ahead and post it.

This information is provided without warranty of any kind.

Remember to backup all files before modifying them. Your safest bet is
backup the entire /usr/share/printconf directory hierarchy.

Reports of success or failure are welcome.

Note: this information is provided without warranty of any kind.

Here is a recipe for adding support for the HP InkJet drivers to RedHat
7.1. This is problematic for two reasons: (1) In RedHat 7.1, the printer
configuration system uses LPRng/Foomatic/MagicFiler rather than LPD,
while the availble RPMs are for LPD, and (2) the printer configuration
tool (printconf-gui, aka printtool) is completely different from 7.0
and earlier and it uses a 'compiled' database rather than a flat file
to store printer information.

So, take a deep breath and remember to backup any files before
overwriting them and also, remember to backup any files before
overwriting them:

0. Download and install the RPMs for RedHat 7 from
   http://sourceforge.net/project/showfiles.php?group_id=16846&release_id=38493
   ghostscript-hpijs-5.50-5.rh7.i386.rpm
   hpijs-0.97-1.rh7.i386.rpm
   You will probably have to --force the installation of
   ghostscript-hpijs since it overwrites the current installation of
   Ghostscript.

1. Go to the supported devices page at
   http://hpoj.sourceforge.net/suplist.shtml and determine which
   driver is appropriate for your OfficeJet. For the sake of
   concreteness, we'll consider the G85. This OJ uses the DJ9xx
   driver, which is one of the "hpijs" drivers from
   http://hpinkjet.sourceforge.net.

2. Go to "http://www.linuxprinting.org/show_driver.cgi?driver=hpijs".

3. Below the text "LPD-O-Matic automagic LPD configuration generator",
   select your printer, such as "HP OfficeJet G85", and press the
   "Generate desc file" button.  This will take you to a foomatic
   printer description. Save this page to a file. The name of the file
   is important: it must be of the form devicename-drivername.foo. For
   this case, I called it HP-OfficeJet_G85-DJ9xx.foo. Check in the
   directory /usr/share/printconf/foomatic/data to get the correct
   punctuation of your OJ's name (i.e., where it uses underscores and
   where it uses hyphens).

4. Copy this file to /usr/share/printconf/foomatic/data.

5. After making a backup of it, edit the file
   "/usr/share/printconf/foomatic/data/00-overview.foo". Find the section
   for your OJ and add the DJxxx driver name to the Perl array of
   driver namess. For the G85, this looks like (see the line with <<<<<
   on it):

    {
      'pnp_cmd' => undef,
      'model' => 'OfficeJet G85',
      'pnp_mfg' => undef,
      'notes' => 'Multifunction device: print/copy/scan/fax.
<p>PC faxing not yet supported.
<p>Same as an <a href="show_printer.cgi?recnum=421842">OfficeJet
G55</a>,
but with an automatic document feeder (ADF) and fax capability.
See that printer\'s entry for scanning and other driver information.',
      'pnp_des' => undef,
      'pnp_mdl' => undef,
      'func' => 'D',
      'id' => 421906,
      'verified' => '0',
      'drivers' => [
        'DJ9xx',    # <<<<< Added this entry first (followed by a comma)
        'cdj550'
      ]
    },

   Note, too, you might want to resolve any differences in 'pnp_des',
   'pnp_mdl', etc., between the entry in 00-overview.foo and the
   device file (from step 3).

6. Also in /usr/share/printconf/foomatic/data, you need to make sure
   there is a symbolic link which relates the driver to the
   device. Note the 'id' field in the 00-overview.foo file. For the
   G85, it is 421906. Issue a command like:

   ln -s HP-OfficeJet_G85-DJ9xx.foo DJ9xx-421906.foo

   replacing the target (i.e., the argument after -s) with name of the
   file you created in step 3 and the link with a name of the form
   drivername-id.foo.

7. Change directory to /usr/share/printconf/util
   Create a file called "list_devices.ps" and add these two lines to it:

   devicenames { = } forall
   quit

   and then run ghostscript like this:

   gs -q -sDEVICE=nullpage list_devices.ps > device-list

   This will create a list of devices which Ghostscript knows
   about. Check this file to make sure that the "hpijs" driver appears
   in it. If not, then the ghostscript-hpijs RPM is not installed
   correctly.

8. cd up a level to /usr/share/printconf and rename the file
   printer_db.pickle to printer_db.pickle.old

   Now, you need to regenerate this file using the modifications you
   made to the foomatic/data directory. This is accomplished by
   running the command (all on one command line, don't actually include
   the backslash character):

   ./util/build_striped_printer_db.py foomatic/data foomatic/rh-data \
       printer_db.pickle util/device-list

   Perform a sanity check on printer_db.pickle by grepping for your
   model name; for example:

   grep 'OfficeJet G85' printer_db.pickle

9. You should now be able to run printconf-gui (aka printtool) and
   create a new print queue which uses the OfficeJet and driver you just
   created an entry for. Don't forget to look at the 'Driver Options'
   panel in the 'Edit Queue' dialog to select the desired printing
   resolution.
