Ubuntu :: Parallel To USB Printer Cable - Shell Command To "mount" It At Startup
May 5, 2011what shell command I should look into that will "mount" a printer that is present in lsusb output, but not present in /dev/usb/? I have a working printer connected with a Parallel to USB printer cable, but after I reboot the machine the printer is not "mounted" (for lack of the correct term?) at /dev/usb/lp0 until I unplug the USB cable and plug it back in lsusb sees it always though.

Jun 3, 2011This post is for an HP parallel printer but I think it should work for at least "some" other parallel printers.I am sure that someone smarter than me will follow up this post with a "well, just do this and that" and you will have your HP Laserjet 6P printer ready to go, but since questions litter the forums of MANY distros on how to get "at least" an HP parallel printer to work, I'll post this anyway.This may or may not work for you if you do not have an HP but you can try it.The install printer box will let you do an install for an HP Parallel and it asks for how it is to talk to it, through CUPS sock or "local host'. When we get through what I recommend you should chose "local host".

Apr 18, 2011When I boot fc14 with an already defined printer connected on the parallel port, then I can use the printer. The printer appears on parallel:/dev/lp0. But, if the printer is not connected during startup, when I connect the printer I cannot use it. Nothing happens. I have no corresponding message using "dmesg" command when I connect the printer.
I cannot make cups see that the printer is connected, using "localhost:631" in firefox. Is it possible to "mount" the printer manually? Using "system-config-printer", the printer has to be "activated", even though it is not used or even connected. Then "parport" module is installed during boot (with other related modules: "ppdev" and "parport_pc").
Then, when the printer is connected, "dmesg" shows :
lp0: using parport0 (interrupt-driven).
lp0: console ready
And, of course, it is now OK to use the printer.
Fedora Hardware :: Deskjet Plus On Parallel Port Working With F13?
Aug 19, 2010I have an old, but still usable, HP Deskjet Plus inkjet printer that I have connected to the parallel port of my Fedora 13 box. I can (apparently) configure the printer using the usual print configuration tools, and have selected the recommend foomatic driver (HP DeskJet Plus Foomatic/pcl3 (recommended)) - but when I try to print the test page the job gets queued and nothing else happens. The jobs simply show as pending in the printer queue.
Current uri is parallel:/dev/lp0.
As a side note, my Epson printer on the USB port works fine, but it's using CUPS + Gutenprint v5.2.6 Simplified. Should I be trying something with a different (e.g. CUPS) driver, or a different way of specifying the foomatic driver, or what?
Fedora Hardware :: How To Install Parallel Port Printer On F14 KDE

Jun 10, 2010I compiled a code on a Linux cluster machine with mpich and ifort. A test run shows that the program works fine. However, it seems that the program is running in serial instead of parallel mode: reducing the number of CPU's from 32 to 3 does not increase the time it takes to run the simulation. Infact, the simulation is slightly faster with 3 compared to 32 CPU's. Unfortunately I have very little experience on the subject.
My questions are:
(1) How can I be 100% sure my code is running in parallel and not in serial mode?
(2) If the code is running serial, what do I need to do to make it run in parallel mode?

For submission I use a jobscript which includes the following lines:

Feb 23, 2010My new Shuttle runs Debian fine, but like most new systems, the old serial and parallel ports are long gone. I have no problems with the serial port - there is a Sourceforge driver to use with most PL-2303 type USB to Serial adapter cables. But, I am having trouble googling up the USB to Parallel connection. There are no lack of USB/Parallel cables, but all that I have found come with canned software for Windows and only for connecting a printer. I have several non-printer devices that connect via the P-Port that I access using a Perl driver from CPAN. Anybody know of an open source *nix driver for any particular USB/PP cable? Or had any experience in moving from the straight PP to a USB/PP connection to a non-printer device?

Hardware :: Driver For USB To Parallel Cable ?
Jan 10, 2010I have been trying to install an old HP Laserjet 4100 printer using an USB to Parallel Cable (Cables Limited USB IEEE 1284 printer cable). The driver provided with the cable worked on windows XP and I was able to print. The cable is also sold as supporting Linux but it seems that is was tested for fedora core 4 and Moschip Support Team wrote me that ubuntu 9.04 was not supported. When trying to install the driver (makefile) I got a lot of errors (see annex) . I have a System 76 PC with ubuntu 9.04, kernel 2.6.28-17-generic, intel(R) Core(TM). Whwn connected the printer is not recognized.
How to install the cable ? Or any trade / model of printer cable really able to work with ubuntu ?

General :: Run Same Script In Parallel From On Session?
Mar 17, 2010I have a shell script to refresh some databases. Currently I open 5 sessions and to execute the five scripts.
Today, as test, I tried to see if I could run two refreshes simultaneously from one session using the '&':
. /refresh.ksh db1 &
. /refresh.ksh db2
The first one ran and the second one started only after the first one was finished. Could it be that the script refresh.ksh contains many commands and those are not pushed to the background? If so, what's the best approach to getting 5 db's refresh simultanously from on session?

Debian :: Dual Boot - Parallel Computing
Oct 11, 2015I was asked to research if it is possible to install a Debian distribution of Linux to HP Z420 Workstations as second OS (dual boot) in our lab. The lab is normally used for Computer Aided Design (Windows 7). The plan is to have parallel computing possible with these workstations on Linux side.
The link for HP Z420 Specs suggests amd64 distrubition should be supported. Tell me If I'm wrong as I have always been interested in software side of things.
Looking for info regarding installation of Debian to HP Z420 workstations as well as using these computers for parallel computing with Debian.
OpenSUSE Hardware :: Parallel Port Printing Under 11.3
Oct 28, 2010I have a Panasonic 3123 dot matrix printer which I am trying to get working on my Dell Vostro 420 running 11.3 (x64). Since Dell decided to eliminate on board parallel ports from their systems I've added one with a Startech PCI1PECP PCI card (uses a NETMOS NM9805CV chipset). I've confirmed that the printer works using an old laptop running Windows 2k with a LPT port running in ECP mode. When attached to my desktop the printer will (usually) shift the pin carriage etc when I perform a cold boot but will not respond when sent a test page in yast or cups (it is detected after a fashion and I have assigned the appropriate ppd from the Omni package).
The following is the relevant out put from lspci, lsmod and dmesg:

Ubuntu :: Dosemu Parallel Port Bit Twiddling?
Jun 1, 2010I've been running an old DOS app that reads and writes the parallel port bits to do a control task. Its worked great running on Ubuntu 6.06 but I can't get the version on 10.04 to read and write the actual hardware. I can't find what is missing from the configuration, as I recall all I did on 6.06 was edit /etc/dosemu/dosemu.conf to uncomment the line:
$_ports = $_ports, " device /dev/lp0 range 0x378 0x37a" in the "Direct Hardware access" section and start the xdosemu session as root. The process runs in the background and has "just worked" for years. This has got me stuck as the last step of migrating from 6.06 to 10.04 -- everything except this, postfix, samba, etc. couldn't have been easier, but I'm stuck now
Yes the new motherboard parallel port is set for 0x378 and it shows in /proc/ioports. I guess it could be defective, but the software reads back the values it writes and thinks its working, its just none of the outputs change and changes on the inputs are not read so the code is stuck waiting for the initial response to its first output.
