[Lpr-discuss] printer stuckness

[Ben W. <be...@va...>]

I've found an interesting behavior with HP printers. Assume lp0 is a
remote LPR printer and lp is a printer connected via parallel port. If
I follow this script:

  lpr -P lp0 /usr/share/printfilters/testpage.ps 
  lpr -P lp0 /usr/share/printfilters/testpage.ps 
  lpr -P lp0 /usr/share/printfilters/testpage.ps 
  lpr -P lp /usr/share/printfilters/testpage.ps 
  lpr -P lp0 /usr/share/printfilters/testpage.ps 

Then the first 4 pages print right after one another but the 5th print
job hangs. After a few minutes the 5th print job comes out.

If I hit the cancel button then the 5th job prints immediately after
the parport job cancels. Also if I select the "send EOJ after job"
option in the input filter then this problem goes away. The "send EOJ"
option the default for parport connected printers? 

What do other people think?
We also need to document this issue. But WHERE should we document it?
