Hello,
I have a Postcript Laserprinter (NEC Silentwriter 2Model 90 to be exact) and I am having some difficulties. I have Printer Parrallel support built as a module, and it loads fine. But the SuSE manual says it should be for most (since I do not have a Hercules card) on lp1. For me, using Yast to configure, I cannot even, reach the printer on lp1.
Now on lp0 I try to print something and this is what happens. There is communication with the printer, and after about 10 seconds of processing it reverts back to the ready state. Running dmesg I get lp0 at 0x03bc, (polling)
Then you know there is data moving. I had an old apple laserwrite, postscript only, and all this on a serial port. not much fun. can you set this printer to print any cleartext emulation? a cat file > /dev/lp1 would show you something: either garbage or readealbe text, possibly with staircase effect. next could be setting the printer to unix mode (LF only instead of CR LF) to enable text printing. If this runs well try to 'cat ps-file > /dev/lp1' (you can do this now as well, but if the printer is silent it can be both a communication problem or "bad" postscript code.
I used to run 0S/2 and I experienced these exact same symptoms. IBM tech support worked with me and we figured out that if I disable polling and use IRQ then everything is fine. Could this go for linux as well? I am assuming from dmesg that I am using polling here as well. Does anybody know how to change this?
polling is standard. I know it can be changed, but not how. ;-( but wait: there is an articke in the german SDB, search for "polling", first hit. the tool you need is called tunelp, it configures the *aktuel used* module, if the module is unloaded and reloaded it is back to polling mode. (that's the article about) very short: compile printing into the kernel and use kernel parameters. <A HREF="http://localhost/support-db/sdb/avaron_lpd_irq_polling.html"><A HREF="http://localhost/support-db/sdb/avaron_lpd_irq_polling.html</A">http://localhost/support-db/sdb/avaron_lpd_irq_polling.html I'm to tired now to translate. A rough guess can be taken from it, though.
One other knote that baffels me. The manual says lp0 is on IRQ5 which is what I have my Sound Card configured to. Now that would explain why it is not working completely, but it would not explain why I cannot even see the printer on lp1 IRQ7 which is vacant. Any ideas would be much aappreciated.
