I get this error whenever I try to print a file...
I found out its coz maybe CUPS isn't detecting the filters, when I tried
raw printing:

[root@FriendlyARM /]# lp -oraw ./abhi.txt
request id is Deskjet-1 (1 file(s))

the page printed...

But Filters are there in /usr/lib/cups/filters:

[root@FriendlyARM /]# ls /usr/lib/cups/filter/
gziptoany imagetops pdftops rastertodymo rastertohp
texttops
hpgltops imagetoraster pstops rastertoepson rastertolabel

[root@FriendlyARM /]# lpstat -t
scheduler is running
system default destination: Deskjet
device for Deskjet: ///dev/lp0
Deskjet accepting requests since Tue Apr 19 23:03:28 2011
printer Deskjet is idle. enabled since Tue Apr 19 23:03:28 2011

Update:

The issue was that there is no pstoraster!

hence only images can be printed.

Anyone knows how to create rasters from mixed graphics without using Ghostscript? I'm facing problems cross compiling ghostscript on ARM...
