Do you mean job and page settings? These are stored in a BMessage and the print_server persists it already for each pair of installed printer and printing application.<br>
<br>
In printer driver hook functions (see <a href="http://www.haiku-os.org/documents/dev/how_to_write_a_printer_driver" target="_blank">http://www.haiku-os.org/documents/dev/how_to_write_a_printer_driver</a>)<br>
 &nbsp;BMessage* config_page(BNode* spool_folder, BMessage* settings);<br>
 &nbsp;BMessage* config_job(BNode* spool_folder, BMessage* settings);<br>
you receive a previous BMessage settings (can be empty at first) and return the new settings.<br>
<br>
You could add PPD related settings into a new BMessage ppdSettings and add that to the provided settings, like (from memory):<br>
BMessage ppdSettings;<br>
ppdSettings.AddString(&quot;key&quot;, &quot;value&quot;);<br>
...<br>
currentSettings.AddMessage(&quot;ppd&quot;, ppdSettings);<div class="Ih2E3d"><br>

Should we use XML for that? If it is so, is there some kind of library that already works on beos/haiku, I should i write a simple parser for those files too?<br>

<br></div>
If you mean other settings I would prefer to also use a BMessage and de/serialize that from/to a file or into an attribute of the spool_folder.<br>
For XML there is a parser in src/libs/expat, you can find other libraries too at <a href="http://www.bebits.com" target="_blank">www.bebits.com</a>, don&#39;t know if there is more in the Haiku tree.<div class="Ih2E3d"><br>

I think at first it suffices to add the current contents of the job settings dialog into a new tab and add another tab for the PPD related settings.<br>
The UI of libprint has to be reworked later anyway, this should not be your primary focus.<div class="Ih2E3d"><br>
