remote printing
 

Is it possible with linux?

Like lets say I have 2 linux boxes, one has a deskjet 832C on it and that works fine. I add the IP address of remote linux machine in the file /etc/hosts.lpd that i created, restart and, Nothing.
-----------------------------------------------------
host machine printcap
HP832C:\
:ml#0:\
:mx#0:\
:sd=/var/spool/lpd/HP832C:\
:af=/var/spool/lpd/HP832C/HP832C.acct:\
:sh:\
:lp=/dev/lp0:\
:lpd_bounce=true:\
:if=/usr/share/printconf/util/mf_wrapper:
-----------------------------------------------------
host machine /etc/hosts.lpd
192.168.1.102
-----------------------------------------------------
remote machine printcap
LINUX_HP832C:\
:ml#0:\
:mx#0:\
:sd=/var/spool/lpd/LINUX_HP832C:\
:af=/var/spool/lpd/LINUX_HP832C/LINUX_HP832C.acct:\
:sh:\
:rm=192.168.1.100:\
:rp=HP832C:\

:if=/usr/share/printconf/util/mf_wrapper:
------------------------------------------------------
Whats wrong? I even setup a samba share and tried it that way, (it randomly works from windows computers, (truly, randomly works depending on where the moon is at in the sky) they are under AD at this place) If I try to print to a windows computer under AD from linux, it pops up on the queue and then sits there doing nothing until i delete it on the windows machine. If I load the UNIX File and printing support, it doesn't care, that makes no difference.

So is it really possible? I have no problem prininting to remote stand alone network printers, but that is because I can just print to the IP. is lpd a severly crippled POS or what? How do I just do it linux to linux and whats wrong with those printcaps?

Re: remote printing
 

Yes, lpd IS a severly crippled POS. Get CUPS (www.cups.org),
install CUPS on both machines, set up the one connected to the
printer as the server, set up the other(s) as a client. It'll work.

Put in another vote for CUPS, I use it to network an 810c deskjet (usb).

alright, i'll give it a shot

(always wondered why people were always talking about CUPS)

I'm successfully printing from Australia and New Zealand to my Europe servers, with lpd...

What's supposed to be the problem with it?

I also have problems with LPD
 

I have to use LPD since the client (an OpenVMS system) doesn't support CUPS, but I think LPD works fine!
I have an "authorization" problem, I think; here there are the las lines of ethereal capture for the client requets:

and for the server answer:

I don't know how to modify hosts.lpd nor hosts.equiv, and I don't even know if this will be the solution!
thanks

lpd is working from VMS!
 

Thanks to the precious help from a great guy of this forum, I succeeded in my job.
I am very glad to tell that now the print from OpenVMS (the client!) works very fine so I can start my Linux workstations (the servers!): it's a step towards the freedom, dont't you agree?
Through one station I can print admittance forms on a standard needle printer and barcode labels on a thermal printer.
NOTE: from VMS I didn't have configured DNS and it works anyway!

-------- Original Message --------
OK, I found the docs about and I wrote a lpd.perms file with only one line:
DEFAULT ACCEPT
I also have understood that it is mandatory to add hostnames to
hosts.lpd and hosts.equiv; at this point I had the message:
Host name for your address (/ipaddr/ ) unknown
but I really succeeded in printing only adding the client name to the DNS (forward and reverse lookup) as suggested in:
http://www.pucmmsti.edu.do/materias/...UT/node24.html (comma 9).

Finally, the print from Linux works fine.
Again, many thanks because: 1) your bootstrap was decidely fundamental to reach the solution, and 2) my heart enjoys seeing in the world there are still so available people like you! :-))
