ghostview (fonts) ?

[misterLu]

I have a pdf file, and when I convert it to postscript file, there is a font problem:

$ a2ps SKMl04w1.pdf -4 -o tmp.ps
[SKMl04w1.pdf (pdf delegated to Acrobat): 13 pages on 4 sheets]
[All: 16 pages on 4 sheets] wrote to file `tmp.ps'

then I try to preview tmp.ps with ghostview:

ghostview tmp.ps

and i get this error:

Code: Select all

Do I miss some fonts ?
How can I get them ?

Only some files generate this problem
