[gentoo-user] got lprng?

[maxim wexler]

Then you're part of a dying breed evidently.

I wasn't able to get cups to work so installed lprng.

For more details on my problem go to the archives and
search against my name and 'print' and 'cups'

This is what I see in my log. It says at least two
spoolers active but ps -A reveals only one.

2006-02-19-14:13:11.018 sarawak [5955] lpd  Do_lock:
flock failed 'Resource temporarily unavailable'
Fatal error - Another print spooler active, possibly
lpd process '5948'
2006-02-19-14:13:11.022 sarawak [5955] lpd  cleanup:
done, exit(0)

After running lprng stop ps-A reveals _no_ lpd
processes and after attempts to print the log reports
that the printer is "waiting".

I used # lpd -F -D1 to read the log according to the
instructions at

lprng.com/PrintingCookbook/index.html

Someone suggested that that particular command started
another spooler. But if everything was alright in the
first place it should have printed (lpr -J file.txt)
before having to look at the log to see what was
wrong.

I can't imagine how frustrated you are at this point.

If you wouldn't mind, I have some troubleshooting suggestions. It appears that 
perhaps you might have some problems with the actual printer interface 
(/dev/lp0), so let's make sure that works well.

FIrst, make sure nothing, even lprng, is using /dev/lp0 - shut down lprng and 
make sure there are no processes left around.

Then run the following command:

    /bin/echo -e -n Hello\\015\\012World\\015\\012\\014 >textfile.txt

And finally

   cat textfile.txt >/dev/lp0

This should print out

Hello
World

followed by a form feed.

Unless this works, there's not much use trying to get lprng (or even CUPS) to 
work.

I am having similar difficulty getting my hp720c working. After trying the 
test you suggested, I still got just nothing on the printer. I have both 
parport, parport_pc, and lp modules loaded, which gives me the lp0 device. 
any suggestions?

	# ll lp0
	crwxrwxrw-  1 root lp 6, 0 Feb 20 14:08 lp0

PS the printer does work in knoppix. Does this seem like probably a kernel 
issue?

Possibly - try running "dmesg" after the "cat textfile.txt >/dev/lp0" and see 
if anything shows in the kernel logs.

after modprobe lp

after cat textfile...
lp0: ECP mode

What you of the CHOAM directorate seem unable to understand is that you seldom 
find real loyalties in commerce. When did you last hear of a clerk giving his 
life for the company? Perhaps your deficiency rests in the false assumption 
that you can order men to think and cooperate. This has been a failure of 
everything from religions to general staffs throughout history. General staffs 
have a long record of destroying their own nations. As to religions, I 
recommend a rereading of Thomas Aquinas. As to you of CHOAM, what nonsense you 
believe! Men must want to do things out of their own innermost drives. People, 
not commercial organizations or chains of command, are what make great 
civilizations work. Every civilization depends upon the quality of the 
individuals it produces. If you over-organize humans, over-legalize them, 
suppress their urge to greatness -- they cannot work and their civilization 
collapses.

Some googling brought up this:

http://forums.gentoo.org/viewtopic-t-416986-highlight-.html

Apparently there are problems with recent kernels and the printer port. 
Apparently ACPI Plug and Play support breaks it. Try the kernel settings in 
that forum post and see if that fixes it.

This looks like an elaborate form of

echo -e "This text should appear on the printer\f" >
/dev/lp0

Which works fine. Also, from apsfilter I was able to
print a test page. So the hardware seems to be OK.

OK, then. Now, if I remember correctly, you require pure text printing using 
the printer's built-in bitmap fonts, correct?

Is this an absolute requirement, or is the requirement just to be able to 
print text files? If the latter, then CUPS may still be an option. CUPS will 
convert the text file to Postscript, then pipe it through Ghostscript and 
print it out on the printer in graphical mode.

The disadvantages of this method are a) it will probably be slower than pure 
text printing, b) the font used to print the text will be something like 
Courier instead of the printer's built-in font, and c) if your print file 
includes printer escape sequences (to change font size, etc.) it won't work 
correctly.

These issues can be worked around by defining a raw CUPS queue and manually 
filtering the input file through unix2dos or something similar, 

Now, supposing that you do require pure text printing, you'll want 
an /etc/printcap entry like the following:

lp:sd=/var/spool/lpd/%P
	:force_localhost
	:lp=/dev/lp0
	:filter=/usr/lib/filters/lpf

Once you've created the entry, run "checkpc" to check for any configuration 
errors, and "/etc/init.d/lprng start" - let's see if that does the trick. I 
think the "force_localhost" may resolve your hostname issues.

This didn't quite do it. But I followed the lprng link
at linuxprinting.org and came across the sample
printcap there which I adapted and...success! Except
for the part where I actually understand what's going
on :^(

Well, I'm glad it's all finally working for you. I know just how 
frustrating it can be to figure out stuff like this.
