Hi all,
I'm trying to configure my box as a printserver over Samba, to connect it
to our HP Deskjet 712C (formerly attached to a laptop, which I want to make
more portable). With a little bit of work I've got PDQ printing fine.
However, if I try printing directly to the parallel port ("cat filename >>
\dev\lp0") I get the message "lp0: compatibility mode" but nothing actually
prints out. I get the same message when using PDQ but something will
actually print. Since this HP printer uses a proprietary file format, I
figured perhaps a plaintext file wouldn't have the instructions to actually
print embedded in it. So I've tried sending files from the Windows laptop
(which has the printer's drivers installed) to the printer over Samba- with
the same results.
First, in what you posted, the use of backslashes (\) where you should be using forward slashes (/) is an obvious error, and it might help to know if it is just in your message to us or in what you are actually doing. (That is, the command should read "cat filename >>/dev/lp0", not "cat filename >> \dev\lp0" -- your version is equivalent to "cat filename >> devlp0", which would create the file devlp0 and copy the other file's contents to it.) In any case, if the printer needs a special driver to work (as this one does; see final item), cat'ing to lp0 is unlikely to work.
Second, what does the [printers] block in /etc/samba/smb.conf look like? Assuming it refrences a spool directory, what does the /etc/printcap entry corresponding to that spooler look like?
Third, when you say ...
... what are you actually doing? Are you printing to a network printer from some application, for example? And do you really mean you get the message "p0: compatibility mode" as part of the failure? If not, please be precise about what you mean by "same" results.So I've tried sending files from the Windows laptop (which has the printer's drivers installed) to the printer over Samba- with the same results.
Fourth, when you say " I've got PDQ printing fine" ... how? PDQ appears to be (from the apt-cache package description; I don't use it myself) just a frontend for workstation use; behind the curtain, lpr or LPRng still needs to be working to support Samba (but not necessarily PDQ) printing.
Finally, have you consulted the Linux Printing Database for HP printers? It's at URL
http://www.linuxprinting.org/printer_list.cgi?make=HP
The Deskjet 712C is listed in the works "Perfectly" column, and the link specifies use of the pnm2ppa driver, and makes some comments about use with PDQ as well.
