Question CUPS ERROR: [Job ???] Request file type is text/plain. (CUPS on ARM architectu

Hi all,
I'm trying to run CUPS on ARM architecture (using MINI2440), The scheduler starts, I added the printer, but I'm not able to print anything to my Deskjet printer.

[root@FriendlyARM /]# lp ./abhi.txt
lp: Unsupported format 'text/plain'!

Error log shows:::

I [19/Apr/2011:23:15:51 +0000] [Job ???] Request file type is text/plain.

No job-ID's are created. Please help, Here's my error log:

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...

Have you ghostscript, or some other txt--> ps conversion?

@bussiness_kid, thts the issue, I'm having trouble cross compiling ghostscript. But m facing problems in that, I found that during the make process, an executablee was generated, which aided in further processing, but since during cross compiling we're getting ELF ARM executables, hence it the build process comes to a halt.

I was thinking on the lines of using QT4 to make an app which generates images out of text+graphics. which could be used with image to raster filter.

But I would still prefer PS.

I also noticed that using CUPS 1.3.11, I was not able to print in the newer laserjet and deskjet printers.

say I was able to print in HP DeskJet 840c and 845c and laserjet 1300n

but not in deskjet 3550 and laserjet P1505

Please suggest something!

Let's fix this bit and the rest may follow. I would expect elf arm executables in your case. That's what you get when you compile C code. What do you want - Java?
There is a Java compiler, but it compiles java; Cups is in C.

I would also say unless you need a network capable scheduler, cups is overkill.
