I'd appreciate the diff being submitted directly to Debian to avoid pointless forks and instead make everyone benefit from it.

Note that CUPS-PDF 2.4.6-1 (Gutsy) already performs a fair dose of auto- detection. Adding the printer is now only a two-click process.

Note that with "-m" in the "lpadmin" you have to give the PPD path exactly as shown in the output of "lpinfo -m".

Steps for Post-install: Check whether there is already a CUPS-PDF queue with "LC_ALL=C lpstat -v | grep 'cups-pdf:/'". If so, assign the name of the first queue found to $queue and skip the next paragraph. Assign "PDF" to the variable $queue, then start a "while" loop checking "LC_ALL=C lpstat -v | cut -d ':' -f 1 | cut -d ' ' -f 3 | grep ^$queue\$" and exit the "while" loop if it fails. In the while loop asign a new name to $queue: PDF, PDF1, PDF2, ... Then create the queue with queue name $queue. Then check with "LC_ALL=C lpstat -d | grep 'system default destination:'" whether there is already a default printer. If not, set the PDF printer as default with "lpadmin -d $queue". -- add/remove the PDF printer in CUPS at installation/removal time https://launchpad.net/bugs/82674 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 82674] Re: add/remove the PDF printer in CUPS at installation/removal time
The script magic you propose for prerm should work well as-is. For postinst, what I would use: lpadmin -p PDF -E -v cups-pdf:/ -m PostscriptColor.ppd -o PageSize=$(paperconf) -o printer-is-shared=no paperconf(1) from libpaper-utils (added to Depends) tells us the default paper size. What I need before that is a way to check: 1) Is there already a printer called PDF? if there is, add a digit to the printer name we're about to create. 2) Is there any default printer already? If there is, don't set as default. -- add/remove the PDF printer in CUPS at installation/removal time https://launchpad.net/bugs/82674 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 82674] Re: add/remove the PDF printer in CUPS at installation/removal time
Detecting all cups-pdf devices is easy, to take down all these queues simply do for q in `LC_ALL=C lpstat -v | grep 'cups-pdf:/' | cut -d ':' -f 1 | cut -d ' ' -f 3`; do lpadmin -x $q done For setting the PDF printer as default check at first whether there is already a default printer with "LC_ALL=C lpstat -d | grep 'system default destination:'" and set PDF as the default printer only if there is no default printer yet. You do not restart CUPS when adding or removing printers with the "lpadmin" command. -- add/remove the PDF printer in CUPS at installation/removal time https://launchpad.net/bugs/82674 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 82674] Re: add/remove the PDF printer in CUPS at installation/removal time
Such a PDF printer makes only sense one the local machine, where the printer queue is defined, therefore CUPS should be advised to no broadcast it into the network. This is done by adding "-o printer-is- shared=no" to the "lpadmin" command: lpadmin -p PDF -E -v cups-pdf:/ -m foomatic:Generic-PostScript_Printer- Postscript.ppd -o PageSize= -o printer-is-shared=no -- add/remove the PDF printer in CUPS at installation/removal time https://launchpad.net/bugs/82674 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 82674] Re: add/remove the PDF printer in CUPS at installation/removal time
Till, thanks for your overview of the situation. CUPS-PDF already provides a generic PostScript PPD which upstream and I heavily edited to include only the bare minimum. We could indeed create a printer called PDF at installation time and delete it at removal time, then restart CUPS to refresh the available printer list. Detecting all existing CUPS-PDF devices at installation and removal is slightly more tricky and would require a heavy dose of scripting magic. Patches are welcome. Making CUPS-PDF the default CUPS printer could be done, but might confuse users who have real printers attached to their computer and make them wonder why printouts are not coming out of their printer by default. -- add/remove the PDF printer in CUPS at installation/removal time https://launchpad.net/bugs/82674 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 82674] Re: add/remove the PDF printer in CUPS at installation/removal time
There should be a special print queue for generating PDF files. Sending
a job to this queue should generate a PDF file from the document sent
into the queue. The PDF file should be easily accessible for the sender
of the job, but other users should not be able to read it.
The package cups-pdf provides the special CUPS backend which converts
incoming PostScript to PDF and puts the resulting PDF into the right
place.
To make this grandmother-proof, the installation of the package should
prepare everything to use this feature. Especially the mentioned print
queue is needed. As the package does not make sense without the print
queue and the print queue does not make sense without the package, the
queue should be created when the package finishes to be installed
(postinstall) and the queue should be removed when the package starts to
be uninstalled (prerm).
Creating and taking down the queue in the postinstall and prerm scripts
is easy. To create it do
lpadmin -p PDF -E -v cups-pdf:/ -m foomatic:Generic-PostScript_Printer-
Postscript.ppd -o PageSize=A4
and to take it down
lpadmin -x PDF
This should be somewhat refined, once when creating the queue it should
be checked whether the queue name already exists and if so, another
queue name should be used (PDF1, PDF2, ...). If there is already a queue
with a "cups-pdf:/" URI, no queue shoud be created.
On uninstallation of the package all queues with "cups-pdf:/" URIs
should be taken down.
A script can also easily find out which local queues already exist and
which URI they have:
lpstat -v | grep -v 'ipp://'
It should also be checked whether a default printer or class is set
("lpstat -d") and if not, the new PDF queue should be made the default.
Concerning the user's choice of the PPD file, he can always change it
with any printer setup tool. More important is grandmother-proofness and
this one reaches only by using a default PPD file.
The PPD file needed is one for a generic PostScript printer. Best is one
which has no tray and duplex options (there is no printer), no
resolution (both PostScript and PDF are vector formats and there is no
raster-based printing engine). It should have only things like color/bw,
quality vs. size, ... (see what options you can set when choosing
"Export to PDF" in OpenOffice.org).
