 |
|
I followed the printing guide on gentoo.org
I get this in /var/log/messages
| Code: |
Jul 9 16:36:22 server usb 1-1: new full speed USB device using address 3
Jul 9 16:36:22 server drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 3 if 0 alt 0 proto 2 vid 0x04B8 pid 0x
0005
|
I try:
| Code: |
echo "hello" > /dev/usb/lp0
|
and nothing happens.
I have an Epson Stylus C40UX - a pretty basic printer, and it work under windows.
Any ideas? Thanks.

snowbum,
Ignore this test. It only works with printers that can take in ASCII text and render it to the paper. First, a lot of printers want a line feed (at least) before putting ink on paper. cat a file that has a few lines of text .e.g. /etc/fstab.
Worse, more and more printers cannot cope with ASCII input and need the host PC to do the ASCII to raster image conversion. They can only print the page image. They are like winmodems, a large chunk of the processing is moved to the host.
The C40 works - just contine with the install.

I did the cat test it mentioned *with* line feeds and that failed. I posted that because I thought if that didn't work surely CUPS would not work. Indeed CUPS is installed and working. I accepts jobs properly. I use the gimp-print driver, which is supposedly the recommended one. The printer won't print. If it was a parallel printer, I start debug about with the port, but it's USB. Do you think I should have compiled the USB and USB printer drivers and mudules? I built the kernel before thinking of setting the that server as a print server. Though I did compile in USB and USB printing and so left it as such. Do you think it would make a difference if they were modules? It looks like they load correctly. I don't understand what it could be. Any ideas where I could look for error messages or how to debug this?
BTW, the USB interface is the old USB 1.1 (full speed? *not* 480mbps). I don't have high speed USB compiled into the kernel.
Many many thanks.

snowbum,
Look in /proc/bus/usb/devices for your printer. if you want a pretty tree view.
If you don't have a /proc/bus/usb/devices file, or its empty, please post just the USB section of your kernel .config file.
Modules make debugging easier but built in works too. You do need the right bits and pieces in your kerenl.

This is a server for my LAN, so the HID and such are not necessary.

snowbum,
That all looks good. The other favoriate thing to go wrong is the /dev location when you set up the print queue at step | Quote: | | Code Listing 4.3: Installing a PPD driver |
in the printing howto.
Look in /etc/cups/printers.conf I have
| Code: | | DeviceURI usb://HP/DeskJet%20960C |
which works (%20= space) Other things that work are /dev/usb/lp0 but not /dev/usblp0 (missing slash)
what happens if you change the DeviceURI line to | Code: | | DeviceURI usb:/dev/usb/lp0 |
