Hi: I tried "everything" to get this Samsung multi function work on my TC 3.51 PC.
No luck - so I gave up - at least for the time beeing. Here is a summary of what I have done. Maybe somebody else can go from here and save the headache I have suffered so far.
Before I quit I installed:
1. the cups.tcz (version 1.4.5) before I tried cups 1.3.11
2. foomatic-rip (because the ML 4500 PPD file mentioned foomatic rip in its source text)
3. ghostscript version 9.0 from repo (because I learned this is the driver which generates pixel output from post script, ghostscript is needed by foomatic-rip and the comamd line command:
$ gs -h
should generate a lising which shows your printer model. Not in my case!)
4. ghostscript-common ( I still do not know what this is for)
5. poppler-bin ( no idea what this for )
There are a few config files which need to be configured.
1. /etc/cups/cupsd.conf
2. /etc/cups/printers.conf (mostly done by the browser interface
http://localhost:6313. /etc/cups/ppd/ this folder needs the PPD file for this printer model - downloaded from
www.linuxprinting.org/download/PPD - although this site had exactly the PPD file I needed - the solution was still not in sight.
4. /tmp/tcloop/foomatic-rip/local/etc/foomatic/filter/filter.conf
this config file needs to be configured to tell the systems where several applications are located. I could not find a description on how to do it. At the end of this filter.conf file I found an error where it said: "preferred_shell: /bin/ash instead of preferred_shell: /bin/bash" So when you work with foomatic so please take a look at this.
5. I was able to handle the "read only" problems of config files, scripts and binaries with the excellent help of our forum members, especially SamK.
(please see theprevious posts)
I have no plans yet how to continue with that SCX 4521F . In some cases it would be cheaper and easier to buy another HP, Canon, Epson or Brother printer. HP is probably the easiest to install under Linux.
Maybe I will try to go back to cups 1,311?
Maybe somebody has the time to add the Samsung SCX 4521F model to the ghostscript.tcz?
