[cups.general] Printing from 32-bit app on 64-bit Linux

[John Jason Jordan]

After all that writing, I think I solved it. Using Nautilus I selected
the folder where I put all the libraries (with the dpkg -x commands).
Right-clicking on it I selected Properties, then Permissions, and I
noted that several permissions were not set. I set them so jjj (me)
could read, write, execute and do anything his pea-pickin' little heart
wanted with them, and then clicked on the option to apply the
permission to the folder and all its contents. 

Then I launched Reader 8.1, opened a file, sent a print job to a
printer and IT PRINTED! Yay!

> First, download the following libraries, being sure to pick the 386
> versions: http://packages.ubuntu.com/feisty/libs/libcupsys2
> http://packages.ubuntu.com/feisty/libs/libgnutls13
> http://packages.ubuntu.com/feisty/libs/libgcrypt11
> http://packages.ubuntu.com/feisty/libs/libgpg-error0
> http://packages.ubuntu.com/feisty/libs/liblzo1
> http://packages.ubuntu.com/feisty/libs/libopencdk8
> http://packages.ubuntu.com/feisty/libs/libtasn1-3
> 
> Next, make a folder to put the libraries into. I made one like this:
> mkdir ~/Desktop/Adobe-CUPS
> 
> Then, extract each of the above libraries to the folder you just
> created using the following command. Note that I downloaded the
> libraries to ~/Desktop:
> 
> dpkg -x ~/Desktop/name-of-i386.deb-file ~/Desktop/Adobe-CUPS
> 
> Next, change the permissions on libcups.so.2
> 
> chmod +x ~Desktop/Adobe-CUPS/usr/lib/libcups.so.2
> 
> And finally, before launching reader you have to run the following
> command (note you will have to change the path if you used a different
> folder than I did for the libraries):
> 
> export LD_LIBRARY_PATH=~/Desktop/Adobe-CUPS/usr/lib:/usr/lib:
> $LD_LIBRARY_PATH
> 
> Then launch Adobe Reader 8.1 as usual. 
> ---------------
> 
> OK, the developers and I worked that out during the beta test for 8.1.
> Now that it has been finally released I installed the release version,
> and then went through the above procedures. Sure enough, I now have the
> drop-down list of printers installed in CUPS in the the Reader 8.1
> print dialog box. But here's the remaining problem: 
> 
> When I send a print job it never appears in the queue. E.g., I open the
> printers folder displaying all the printers I have installed. Normally
> when I send a job to a printer it appears under the icon for the
> printer for a bit while the job is printing, like "1 print job." When I
> send a print job from Adobe Reader nothing ever appears under the icon
> for the printer. 
> 
> Note also that this appears to be a problem only on 64-bit Ubuntu. I
> heard from at least one other user on a different 64-bit distro (Fedora
> 7?) and he had no problem. So evidently the source of the problem is
> that 64-bit Ubuntu does not install these 32-bit libraries, but other
> distros do. And users of 32-bit distros never have a problem.

> I'm hoping that the collective wisdom of the CUPS gurus here will lead
> me to the final answer. Is it yet another library that I'm missing?
> Something else? Any suggestions welcome!
