thanks for the effort. But did it print a complete testpage correctly? Yast and Cups detects my HP 4L but HPLIP doesnot. Nevertheless no driver prints the the testpage correctly, just garbage, page after page. So it is not the problem of finding the printer or sending data, but some problem with the header or the characterset… Could it be a Problem???
Other than the page settings being wrong (the last few lines printed on a new page, probably because it thought it was letter and not A4 paper) the test page was fine using only cups with the default gutenprint driver.
With a bit of fine tuning, printing should be fine.
I don’t think hplip will support the printer unless you have it connected to an hp print server. (You can pick one up quite cheaply on the auction sites and it will allow you to share the printer over the network.)
Try checking your parallel cable and your pc bios settings to allow bi-directional communication.
I have always found the hp4l very reliable.
Looking at your reply in this thread: Parallel port in opensuse 11.2 64-bit does not work. - openSUSE Forums
You never mentioned that you were using a usb to parallel converter.
At a rough guess, I would say the problem is not in the printer or openSuse, but in the converter setup.
Check the coverter is set up correctly and try copying a text file directly to the printer using something like:
cp file.txt /dev/lp0 or whatever the printer port is called.
I tried to send text or ascii files and signs directly and see that the data led is flashing so the HP4L receives something, but the actual print command seems to be missing. It starts printing when I send a page from cups or Openoffice but the printout is garbage and could only be stopped by brute force.
Lpr -Plaserjetname file.txt
testtext > /dev/lp0
The reason I was looking in desparation at the other Thread is that my windows system with NetMos Drivers sees LPrt3 instead of LPRT1
It is not depending on the Bios, because then Suse 11.1 woud not work!
Which parallel port drivers would I have to look at, to see if there is a difference between what 11.1 and 11.2 does to the same hardware differently? Again the same applies to ubuntu versions in live mode, so I doubt that there is anything wrong with the installation of Suse 11.2.
Perhaps it would be easier to find out how opensuse sets the parameters.
Perhaps the old days when the card was configured manually with jumpers was better - at least you didn’t need to rely on manufacturer’s support.
If you look on fleabay, you will find that parallel hp jetdirect print servers are pretty cheap and guaranteed to work with not only hp but most parallel printers. Once you have used one for networked printers, you’ll wonder why you never used one before. Probably also be less trouble in the long run.
