I have a problem with very slow printing after replacing 4.1 instalation
with new 5.4 instalation (clean install, not upgrade). The printer is HP
4L, and i use it with up to date CUPS (all packages + gimp-print). With
both CUPS ang gimp-print drivers and default port settings the dokument
printing speed is about 8k each 1 minute (acording to CUPS web interface).
There are no error messages from the kernel. With hint.ppc.0.falgs="0x20"
or "0x80" there is the same effect.
With hint.ppc.0.falgs="0x20", "0x40", "0x48" and "0x88" CUPS web interface
shows taht first 32k are sent instantly. Then 'Interrupt storm detected on
"irq5: lpt0"; throttling interrupt source' kernel error message apears and
the rest of the document prints slow, as in the first example.
I tried this with several standard and HP bidirectional cables. I also
tried all possible BIOS settings for the port.
The old 4.1 instalation prints without problems.
I had the exact same problem, except with a Deskjet 932C. Someone on the
list said "man lptcontrol" and set your printer to "poll".
I used this command:
% lptcontrol -p -d /dev/lpt0
and it fixed my problem.
