Bugzilla – Bug 116936
No printing via parport in ECP/DMA mode after printer setup in YaST
Last modified: 2005-09-15 09:31:31 UTC
For background information see https://bugzilla.novell.com/show_bug.cgi?id=116655#c52 Proposal for a text for the release notes: ------------------------------------------------------------------------ Reboot may be required after parallel-port printer setup with YaST. If printing doesn't work if a parallel-port printer was set up with YaST, please reboot but don't run the YaST printer setup for testing whether it works now. Reason: YaST must re-load the parallel-port kernel modules to autodetect new attached parallel-port printers. The parallel-port kernel modules hang up when they are re-loaded if the parallel-port is used in ECP/DMA mode. Therefore the ploblem can be avoided if neither ECP nor DMA is set for the paralle-port in the BIOS. ------------------------------------------------------------------------
Let's add it without giving too much details. Karl, please add this.
It is in as follows (on aj's request) - just for your info, Rebecca: <sect3 id="pp_printer" status="2005-09-14"> <title>Using Parallel-Port Printers</title> <para> Reboot may be required after parallel-port printer setup with YaST. If printing does not work when a parallel-port printer was set up with YaST, reboot and then do not run the YaST printer setup again for testing. Only parallel-port printers in ECP/DMA mode are affected. </para>
Is it too late for proofreading? <sect3 id="pp_printer" status="2005-09-14"> <title>Using Parallel Port Printers</title> <para> Reboot may be required after setting up a parallel port printer with YaST.

Thanks - it's too late for the box product, but we can publish some more update on the server. Johannes, is ECP or DMA mode correct or is it one mode called "ECP/DMA"?
Both "ECP or DMA" and "ECP/DMA" are o.k. Technically I would prefer "ECP/DMA" because in fact it is one mode - the "ECP" mode - which uses DMA (Direct Memory Access). It is DMA what actually fails (there are "DMA write timed out" messages in the logs). Therefore I appended "DMA" to "ECP" to make it more clear that the issue is in fact about "DMA". The user would find nothing of interest in the logs when he searches for "ECP".
Rebecca, is it okay to write "ECP/DMA"? See comment #5 .
I did some googling. Please write "ECP DMA mode."
thanks - done.
