I will be moving this post to solve soon, I have now manage to print using my Slackware machine. On the way print on Windows and Ubuntu. I have to say I got the keys from the Ubuntu machine installation. Here
there is not much to say there a part from that link to ijs_server_epsonepl to usr/bin, the rest would be similar to what I describe bellow.
Let move to more slackware-machine.
What I have done:
Download and compile from here
(On that order)
On my search to create scrip to I found this page a year old which describe depend for foomatic but I am not 100% sure of that, you can found it here
But I used the Slack Build type script to compile. I also used current and give a version number, to do that I need to change the package original version or the script give error.
after all in (I could not wait to the other post to see if I was compile it well) I downloaded the "epsoneplijs-0.4.1.tgz" suggested earlier in this post.
I didnt compile ijs_server_epsonepl as I did earlier on on this, you could read back it you want to know how. I did check and I didnt need to link it as it was in a system path.
Then I did what Debian-install script say on "epsoneplijs-0.4.1.tgz" but manually, comping the folder from driver/opt/printer to slackware folder.
I took the pdd ziped and uncompress it to a bear pdd and the guessed as if you type man foomatic-datafile the description is very similar to ppdfile and it even give me the feeling there are the same so I ran:
(Worse to mention here before doing that I reverse to cups 1.5 and I have not printer installed)
foomatic-ppdfile -t cups -d epl6200l -p Epson-EPL-6200L >/..../Epson-EPL-6200L-epl6200l-cups.ppd
That gave me not reply(its different in Ubuntu-in Ubuntu create the file and the you need to add it), but I went look at cups and the printer was already installed,so I tested as before in the command line:
lp -d printer -P 2 /......path to/Osc_footprint3.2_to_print.ps
Very happy to see the printer flashing getting read to print.
There still some question and maybe better package compilation, also looking a new db there was a 6200L with a rename and add the one from "epsoneplijs-0.4.1.tgz" maybe its not need it (maybe further test).
