[cups.general] Delay before printing in more recent Linux distributions?

[Nick Rahl]

This is the SNMP code getting the final page count; add "*cupsSNMP: False" to your PPD file and the delay will disappear.


Thanks Michael,

I added:

*cupsSNMP: False

To the bottom of the PPD file just before:

*% End of ZEBRAEP2.PPD, 67437 bytes.

In /etc/cups/ppd/

....and restarted cups, but the delay is still present, and I'm still 
getting the error in my log.

What am I doing wrong?

I'm using CUPS 1.4.5. My printer is a Zebra/Eltron 2844. This 
delay/error is also present in 1.4.3, but is NOT present in 1.3.8.

And once the printer light starts blinking (after the SNMP delay), is it 
normal for it to take another 5 seconds to download the data before 
printing it? It's a one page, 70K .png file. Are there any network 
settings that could be tweaked, like compressing the file, changing 
packet size, etc?

3 seconds is spent on the loop:

I [02/Dec/2010:15:20:41 -0500] [Job 3195] Printing page 1, 65% complete...
D [02/Dec/2010:15:20:41 -0500] Discarding unused job-progress event...

event...
I [02/Dec/2010:15:20:41 -0500] [Job 3195] Printing page 1, 67% complete...

and 3 more seconds on the loop:

D [02/Dec/2010:15:20:43 -0500] [Job 3195] Read 8192 bytes of print data...

Thanks again,
