hplip should not use pstoraster anymore

[Marc Schiffbauer]

as of version 9 of ghostscript-gpl it does not provide pstoraster anymore but gstoraster instead. hplip needs to be fixed so that it will just use that other tool.

A workaround is create a symlink from gstoraster to pstoraster in ghostscript to make hplip work again.

Please see that gentoo bugreport for more details: https://bugs.gentoo.org/show_bug.cgi?id=388155

Since app-text/ghostscript-gpl-9.02 (?), gs does not provide the "pstoraster" filter anymore, which has been renamed gstoraster.

ghostscript-gpl-9.04-r4 provides a symlink
/usr/libexec/cups/filter/pstoraster -> /usr/libexec/cups/filter/gstoraster for convenience until all print drivers are fixed.

hplip needs to be fixed to use gstoraster instead of pstoraster

I am the maintainer of hplip, so why did you assign this bug to the printing team only?

Sorry, I assumed you were a member of the printing herd.

Are you sure hplip does not work with gstoraster? The source code of hplip
contains no trace of pstoraster besides the foomatic-rip-hplip perl script
which is not installed. Try rebuilding cups and test again. See comments 7-9
from bug #372145.

I just removed the pstoraster symlink again that I added manually, then rebuilt cups.
A simple "lpr /etc/hosts" does not work then anymore and I can find this in the cups/error_log:

E [02/Nov/2011:20:12:52 +0100] Unable to execute /usr/libexec/cups/filter/pstoraster: No such file or directory
E [02/Nov/2011:20:12:52 +0100] [Job 32] Unable to start filter "pstoraster" - No such file or directory.
E [02/Nov/2011:20:12:52 +0100] [Job 32] Stopping job because the scheduler could not execute a filter.

Also, rebuilding hplip does not fix it.

Strange, why does "qlist ghostscript-gpl" list pstoraster? Do you remove it manually in the ebuild?

gnaaa that was the recent ghostscript update, that fixed it.
