Holy crap batman!!!
I can now print!!!
1st I went to the GUI printer in RHEL and try to set the LPD/LPR Parameters. I was able to print but the problem is still very persistent on defining PPD. Ok...what the hell, I used Generic ESC/P Epson Printer and I knew it will turned out to be a postscript when I try to print. Disgusted with the result I deleted it in the GUI Printer Setup. I went to my remote terminal and logging (1st floor bldg) to ssh.
Reading lpr points to lpadmin. Reading lpadmin, I see stuff pertaining to the old setup commandline...so I just did.
-p = Printer Name (okidata microline 321)
-E = enable/acceptting
-v = device/uri
-i = interface (Epson FX-2175)
#lpadmin -p oki321 -E -v lpd://192.168.1.5/oki321 -i efx2175
wtf!!! it gave me "No files or directory found."
I went to /usr/sbin and gave another command with the samething/result. I went back to the server (dammit 4 flrs of going up & down) and try again the IPP instead of LPD/LPR but to my suprise!!, the lpd/lpr GUI setup has a complete parameters of what I commanded with "lpadmin" but instead of the PPD printer driver its now using "Local Raw Printer" which is what I want!!!
At the end of the day!!!! I can now do what we used to do with the old dot matrix printer!!!
Thanks fantasio for this reply...
"lp command still exists when using cups, lpd and cups are both printer/queue manager"
It made me think more than the GUI.
