I've mentioned this before, here, but with a laser printer connected via the lp0 port.
I have a new laser printer, a Brother HL2140, that normally works just fine when installed using the CUPS interface per OpenPrinting's instructions (with one minor modification I had to add because the base driver without the CUPS installation did not work.
Every so often, which actually appears to be every time the printer goes into power-saver mode, when I try to print something, I get this response in lpstat -t:
[mhr@mhrichter ~]$ lpstat -t scheduler is running no system default destination device for HL2140: usb://Brother/HL-2140 series device for HPOJ4315: hp:/usb/Officejet_4300_series?serial=CN7AJH318W04GQ HL2140 accepting requests since Sun 23 Nov 2008 02:38:56 PM PST HPOJ4315 accepting requests since Sun 07 Sep 2008 12:52:14 AM PDT printer HL2140 now printing HL2140-2188. enabled since Sun 23 Nov 2008 02:38:56 PM PST Printer not connected; will retry in 30 seconds... printer HPOJ4315 is idle. enabled since Sun 07 Sep 2008 12:52:14 AM PDT HL2140-2188 root 18432 Sun 23 Nov 2008 02:38:56 PM PST
At one point, through some strange combination of:
System->Administration->Printers Disable the printer cancel the print job (sometimes) disconnect the printer (USB cable out) power down the printer power the printer back on and wait for it to come ready reconnect the printer re-enable the printer
liberally sprinkled with 30 second waits, I used to be able to get the printer to come back on line and print.
Now I can't seem to get the <censored> thing to come back at all.
Any suggestions on what to do to make this work? I suppose I could reboot, but that _really_ defeats the purpose of using a USB printer in the first place.
FTR, I also have an HP OfficeJet 4315 on a USB connection to the same system, and I _never_ have this problem with it.
I'm running CentOS 5.2 x86_64 with all the latest updates, using the printer drivers from the OpenPrinting online database:
brhl2140lpr-2.0.2-1.i386.rpm cupswrapperHL2140-2.0.2-1.i386.rpm
Stumped.
