Installing printer with slash "/" in driver name fails

Bug #39976 reported by Tormod Volden
Affects Status Importance Assigned to Milestone
gnome-cups-manager (Ubuntu)

Bug Description

I try to configure a printer using the PPD file provided by the printer manufacturer. The PPD file uses a NickName containing a "/" (slash).

Adding the printer silently fails. I can choose the printer driver in the GUI (where I can see the slash in the listed name), but after clicking Apply and thus closing the Add Printer window, the printer does not show up in the Printers window.

If I manually edit the PPD file and replace the slash with a "-" (hyphen), I can add the printer without problems.

Here is an example PPD file. The same happens with other PPD files too.

Just for fun, I edited one of the Ubuntu-delivered driver files, /usr/share/cups/model/cups-included/Epson/epson24.ppd, and put in a slash in the nickname. It failed to set up the printer. This is not a problem with any particular model, it's for all PPDs having a slash in the nickname. I guess the PPD "standard" allows slashes in the nickname.

I confirm this bug using dapper 20060418.
The problem is in gnome-cups-manager and is related to the "Foomatic/" (note the slash!) indication used in *NickName of PPDs. The "Foomatic/" indication is used to group together different drivers for the same printer model. I marked this bug major since it affects a lot of PPDs in the following packages: cupsys-drivers-gutenprint, foomatic-filters-ppds and

As a workaround, I made a copy of the PPD file I wished to use and then editted the new copy - the diff is below.
