Comment 5 for bug 2000275

The actual permissions on the socket that the error complains about:
$ ls -l /run/user/1000/at-spi/bus_1
srwxrwxrwx 1 usern usern 0 Oct 21 09:02 /run/user/1000/at-spi/bus_1

I do have the ttf-mscorefonts-installer package installed, but even ps files with no fonts do not display:
A line drawn on the page show on the evince initial display page but no preview, no printer output.
$ cat tst.ps
%!PS
newpath
72 72 moveto
200 200 lineto
stroke
showpage

The printer is an HP Officejet J3680 All-In-One (obsolete), but other programs do successfully print ps to it.

In the past, I used evince to print my ps files, but now I have to use qpdfview (text files generated by a2ps).
