Printer (dmesg) error
I am setting up a printer for a friend. I've built the box using (Gnu/Linux), Slackware-current, Kernel 2.6.7. I have the same setup. Currently the only way I have access to my friends machine is across the Internet via SSH, so I'm unable to manually check cabling at the moment.
On my Slackware box, printing works fine. CUPSd is not installed on either machines, nor do I plan to use it. The setup, LPRng, is not really in question.

The questionable printer, a Xerox M750, does in fact work under MS Windows 98.
When sent cat somefile > /dev/lp0, the printer just starts blinking but nothing is printed. Same results when sent gs -dSAFER -dNOPAUSE -sDEVICE=pcl3 -sOutputFile=\|lpr file.ps
Looking at the dmesg output produces the lp0 on fire error message, which is not useful.

The only thing I've noticed that was not the same as with my machine, which prints fine, is in the dmesg output.

My box, which prints fine, shows:

parport0: PC-style at 0x378 [PCSPP,TRISTATE,EPP]
parport0: Printer, EPSON STYLUS COLOR II
lp0: using parport0 (polling).
lp0: console ready

The Xerox (non-printing printer box) shows:

parport0: PC-style at 0x378 (0x778) [PCSPP,TRISTATE,EPP]
parport0: irq 7 detected
parport0: Printer, Xerox DocuPrint M750
lp0: using parport0 (polling).


What's missing is the line lp0: console ready. Plus I noticed the additional line
parport0: irq 7 detected.


My question is just, has anyone seen the absence of lp0: console ready line in their setups, and know what may have caused this? Such as a bad cable or incorrect BIOS port setting, or something else possibly?
I'm thinking it might be a bad cable.

NAME

       foomatic-getpjloptions - <put a short description here>

SYNOPSIS

       foomatic-getpjloptions device

       foomatic-getpjloptions hostname port

DESCRIPTION

       foomatic-getpjloptions  Sends  a  set of PJL commands and reads back the PJL options and status from a printer over a network connection or
       device bidirectional interface such as parallel, USB, serial.  printers to standard output. The output can be piped into foomatic-addpjlop-
       tions to add options to the database.

   Options
       device	 The interface to which a local printer is connected, e.g. /dev/lp0, /dev/usb/lp0, /dev/tty00, etc.  For a parallel port, you must
		 have bidirectional support enabled at the BIOS level and the parallel port driver must support  the  bidirectional  mode.   Check
		 your parallel port BIOS settings for  EPP/bi-directional mode.

       hostname  Host name or IP address of a network printer (HP JetDirect, DLINK, etc.).

       port	 Port  on  which  your	network printer listens for socket (Appsocket) connections.  Most common ports are 9100 (JetDirect), 10000
		 (DLINK).  Usually you can configure the port via a configuration interface.

EXIT STATUS

       foomatic-getpjloptions returns ???

AUTHOR

       Manfred Wassmann <manolo@NCC-1701.B.Shuttle.de> for the foomatic project using output from the associated binary.  Modified by Patrick Pow-
       ell <papowell at lprng.com> to provide betters support for network printers, error messages, and remove CR and FF from output.

WARNINGS

       Uni-directional	protocols  as remote LPD are not supported as no status is returned.  Some network print servers which attach to a printer
       parallel port do not support bidirectional mode.
