Ch340s Usb Parallel Driver
I have a laser cutter connected via a generic USB to parallel. Send raw data to USB parallel port after upgrading to 11. Electronics CH340S Device. Jun 03, 2008 USB to LPT/Parallel in windows XP. I have tried to install USB to Paralell (LPT) controller driver in Windows 98SE as ECP Priner Port with driver from.

I have a laser cutter connected via a generic USB to parallel adapter. The laser cutter speaks HPGL, as it happens, but since this is a laser cutter and not a plotter, I usually want to generate the HPGL myself, since I care about the ordering, speed, and direction of cuts and so on.
In previous versions of Ubuntu, I was able to print to the cutter by copying an HPGL file directly to the corresponding USB 'lp' device. For example: cp foo.plt /dev/usblp1 Well, I just upgraded to Ubuntu 11.10 oneiric, and I can't find any 'lp' devices in /dev anymore. What's the preferred way to send raw data to a parallel port in Ubuntu? I've tried System Settings Printing + Add, hoping that I might be able to associate my device with some kind of 'raw printer' driver and print to it with a command like lp -d LaserCutter foo.plt But my USB to parallel adapter doesn't seem to show up in the list.
What I do see are my HP Color LaserJet, two USB-to-serial adapters, 'Enter URI', and 'Network Printer'. Meanwhile, over in /dev, I do see /dev/ttyUSB0 and /dev/ttyUSB1 devices for the 2 USB-to-serial adapters. I don't see anything obvious corresponding to the HP printer (which was /dev/usblp0 prior to the upgrade), except for generic USB stuff. For example, sudo find /dev grep lp produces no output. I do seem to be able to print to the HP printer just fine, though. The printer setup GUI gives it a device URI starting with 'hp:' which isn't much help for the parallel adapter.

The CUPS administrator's guide makes it sound like I might need to feed it a device URI of the form parallel:/dev/SOMETHING, but of course if I had a /dev/SOMETHING I'd probably just go on writing to it directly. The /dev/usb/lpX device files you are looking for are provided by the usblp driver. It seems in Ubuntu 11.10 though, that this driver has been blacklisted.
See the /etc/modprobe.d/blacklist-cups-usblp.conf file: # cups talks to the raw USB devices, so we need to blacklist usblp to avoid # grabbing them blacklist usblp If you want to send data directly to the device still, you can temporarily load the driver with modprobe usblp (the blacklist only prevents the driver from being automatically loaded). Once you are done, you can unload it with modprobe -r usblp.
