cups lpd - Utlimate slow printing solution - Ask Ubuntu

i've been under ubuntu 10 years now, there problems have thick skin! 1 of them, slow printing delay problem, never solve! today start printing 20 copies of 1 page pdf document, after half hour nothing happened! search solutions on net since years, found any. i'm sure not brand or model related problem, since tested many printers different brands, seems raw file generated printer big, takes long time generated , transmitted printer.

i wonder if find workarounds in post, in cmdline, or @ least, identify what's wrong, @ process stucks, know nothing in cmdline printing, can please give cmd lines test , debug printing process.

edit:

it seems printing single page 1 time give no delays, if try print say, 20 copies of same page, seems it's generating whole 20 pages, giving long delay.

edit 2: here debug info: http://pastebin.com/yzfgp66v

edit 3: after rebooting, printing starts @ boot process (i understand cpu issue!)

edit /etc/cups/cupsd.conf file, find section "loglevel" change "info" "debug" save , exit restart cups

# /etc/init.d/cups restart 

or ubuntu

$ sudo /etc/init.d/cupsys restart 

then enter command view log

tail -f /var/log/cups/error_log

with cups loglevel set debug, cups error_log show programs executed during print job.

generally there 2 data paths taken during print job;

1) hpijs driver path

2) postscript driver path. both data paths use "hp" backend.

for hpijs path, errors near ghostscript command (gs) command. gs command invoke hpijs driver.

for postscript path, there no gs command. postscript passed directly "hp" backend , printer.
