For all HP multi-function devices the functionality of sending documents from the PC as fax is supported by the HPLIP package. No other manufacturer offers this with free software.
Unfortunately, the version 2.7.7 of HPLIP which we ship with Gutsy has a bug in the fax part of the printer driver and therefore is not able to convert the input files into the format needed by the fax components of HP's multi-function devices. This makes the fax function of all multi-function devices from HP not working, and so a basic functionality gets lost in Ubuntu Gutsy
Fix of the bug
HP has fixed this problem in HPLIP 2.7.10 and comparing the source code showed that only a small fix in one source file is needed. The fixed packages which I am proposing here has a patch added to apply exactly this fix.
shows the changes which only affect this one file of the fax part of the printer driver hpijs. What has changed is only the handling of temporary files. I have tested it with both HPLIP 2.7.7 and 2.7.10 and it works as expected. There are also no CUPS/AppArmor problems with the new handling of temporary files (I did "sudo aa-enforce cupsd" before testing).
