[Printing-architecture] Created ../pwg/fsg/April2003_meeting_slides directory for FSG presentations

[Printing-architecture] Created ../pwg/fsg/April2003_meeting_slides directory for FSG presentations

[Claudia Alimpich]

I created a directory under the fsg directory where we can put our FSG
presentations for the PSG/FSG meeting on April 1st.
   ftp://ftp.pwg.org/pub/pwg/fsg/April2003_meeting_slides

If you don't like the name of the directory or where it resides, we can
change/move it. I thought that it would be better to have all of the
presentations in the same directory instead of under the individual
sub-directories.

I placed the DRAFT version of the JT presentation there already and will
replace it with the FINAL version once we review it this Tuesday and make
changes.

I have nothing against the directory name, but it would be nice if I 
could actually upload files to the directory.

I tried from my local machine and from linuxprinting.org (see the 
sessions below). From linuxprinting.org I can change into the correct 
destination directory, but when I try to upload a file, it simply hangs, 
until it reaches the FTP connection timeout after 5 minutes. Trying from 
my local machine gives only errors as shown below. "scp" upload does not 
work, there is no SSH daemon listening on port 22 of ftp.pwg.org.

I have put up the slides on linuxprinting.org for now:

http://www.linuxprinting.org/till/tmp/talk_pwg2003.pdf
http://www.linuxprinting.org/till/tmp/talk_pwg2003.sxi

The ".sxi" file is created with OpenOffice.org 1.0.1 under Mandrake 
Linux 9.0.

I can download and view Claudia's files on the FTP server with Mozilla, 
only upload with "ftp" or "gftp" does not work for me

Can someone check the server and fix the problem or at least upload my 
files?

Thank you.

To make download easier, I have added the following formats for my slides:

http://www.linuxprinting.org/till/tmp/talk_pwg2003.pdf.zip
http://www.linuxprinting.org/till/tmp/talk_pwg2003_POOR_QUALITY.ppt

the really shortest is the PowerPoint version which I have generated 
with OpenOffice.org, but the slides in it look ugly, the background is 
messed and the logo is missing, but one can at least read the text and 
the diagrams.

Oi,

as wide parts of the US are deeply buried under snow, here is a 
text-only version (below) to be readable also from cell phone displays 
or PDAs (so that fixed phone and/or electricity are not needed).

Here are also HTML versions:

http://www.linuxprinting.org/till/tmp/talk_pwg2003_html/talk_pwg2003.html
http://www.linuxprinting.org/till/tmp/talk_pwg2003_html/text0.html

linuxprinting.org and Foomatic

Till Kamppeter, MandrakeSoft, France
PWG/FSG OP Meeting, March 31-April 4, 2003

Summary

- What is Foomatic?
- How did Foomatic emerge?
- How does Foomatic work?
- What is planned for the future?
- What is Foomatic?

Foomatic: Universal Printing Infrastructure

- Database about how printers are supported by free software
- Most complete database: Lists all free drivers and around 1000 printers.
Contains also information of how the drivers are executed (Command line, 
options)
- Easy setup of printers under all spoolers

What is Foomatic?

- PPD file generator for all free printing systems (CUPS, PPR, PDQ, LPD, 
GNUlpr, LPRng, CPS, no spooler)
- User has access to all the driver's options when printing
- Scripts for administration/printing with the same interface for all 
spoolers
- Inofficial standard used by Mandrake, Conectiva, Red Hat, SuSE, 
Debian, KDE Print, ...

How did Foomatic emerge?

Foomatic: A Short History
- Started 1998 by Grant Taylor, author of the Printing HOWTO
- CUPS-O-Matic In early 2000, shortly after first CUPS release, later 
PDQ-O-Matic
- In August 2000 I started at MandrakeSoft to switch Mandrake 7.2 to 
CUPS as the first distro.
- To not loose printer support in Mandrake 7.2, I entered the execution 
details of all drivers.
- Since August 2001 I am project leader.

How does Foomatic work?

- XML-Database consisting of entries for
   o Printers: Contains make, model, comments, support quality, ...
   o Drivers: Contains name, type, command line prototype, list of 
supported printers, ...
   o Options: Contains name, type, possible settings, for what 
printers/drivers, what to insert into command line/print job
- From this is derived which drivers
with which options support a printer

How does Foomatic work?

- This data forms the pages of linuxprinting.org
- The same data is used to generate PPD files:
- The user chooses printer and driver
- An Adobe-compliant PPD file for the printer/driver combo is made
- The user sets up a print queue with this file and the universal 
Foomatic filter "foomatic-rip"

How does Foomatic work?

Foomatic filter
- "foomatic-rip" filter converts PostScript to the printer's native 
language.
- Filter is Perl script, reads printer capabilities from PPD file 
without libraries
- Filter receives user's settings via spooler or embedded in the job's 
PostScript
- Filter sets up GhostScript command line from info of the config file 
and the user
- Also inserts settings in job (PS, PJL)

How does Foomatic work?

- Interaction with applications/frontends
- Applications produce PostScript to print
- Options can be set on the command line: "lpr -P lj -o Resolution=1200 
file.ps"
- KDE Applications use GUI "kprinter" which gets capability info from 
Foomatic PPD or CUPS
- Other GUIs: XPP, GTKlp (CUPS), GPR (PPD)
- The PPD files are also used for PPD-aware apps (as OpenOffice.org) or 
Windows/Mac clients.

How does Foomatic work?

Same interface for administration/usage of every spooler

foomatic-configure
- Administration of print queues (add, modify, copy, ...)
- Adding queues with one command line under any spooler

foomatic-printjob
- Tool for printing and managing jobs
- Unifies functionality of "lpr", "lpq", "lprm", "lpc" also for spoolers 
without such commands

What is planned for the future?

- Printer/driver classes
   o Classes contain printers or drivers with common features (as all A3 
printers, all PCL5, ...)
   o Option/choice constraints can specify classes
   o Class XML files contain common info as printer language, comment 
text snippets, ...
- Option conflict handling (as duplex on transparencies)
- PickMany, String and Password option types

What is planned for the future?

- "pstoedit" driver entry for HP-GL/2 plotters
- Links to PPD/UPDF files in database, hosting these files on 
linuxprinting.org
Free HP and Kyocera PPDs already available.
- Automatic Foomatic data generation for UPDF files with Omni
- GUI for Foomatic tools
- Printer auto-detection
- Auto-config of OpenOffice.org, GIMP, ...

Final words

Foomatic ...
... is the most complete printer/driver compatibility database
... generates Adobe-compliant PPD files
... has a universal filter for all spoolers
... provides tools for printer administration and printing for all free 
spoolers
So Foomatic is already one of the best solutions for 
printer/driver/spooler integration, but ...

Final words

- Currently, 90 % of the work on Foomatic is done by me
- More developers needed to implement important, but still missing features
- Database must be kept up-to-date with new printer models
- Publishing of PPDs/UPDFs as free software by printer manufacturers 
needed, to add these files to linuxprinting.org
