[hpoj-devel] Double-sided printing

[Bill W. <wo...@ne...>]

  I just received the double-sided printing attachment for my G85. The
  instructions indicate that you have to click the Double-sided option
  in the Windows software.

  Uh-oh.

  I just figured everything would come out double-sided by default
  once I added the attachment. If this is not the case, I'd appreciate
  any tips on enabling it.

I'm using the cdj970 ghostscript driver and use the -dDuplex=2 option. 
I don't know if it will work with the cdj600 driver.  I think 2 is flip
on long edge, 1 is flip on short edge, and 0 is single sided.

Be warned that it is slow.  It waits for a while before it flips the
paper.  At first I thought it was crashed or thinking really hard or
something.  I think it waits for the ink to dry before it sucks the
paper back in to flip it.

  That's great! I'll give it a shot and let you know. Thanks.

  That's what the manual says.

  Where is this cdj970 driver you speak of? I had my head in gs 5.10,
  5.50 and 6.50 today (long day). Didn't see it anywhere.

  Meanwhile, I tried to compile the new inkjet drivers (DJ9XX). I say
  compile since I'm running a Debian system and while I was able to
  create .debs from the RPMs with alien, the package name was
  different and thus didn't replace gs nor its dependencies. The
  install therefore failed because it wanted to overwrite existing
  files which dpkg won't let you do.

  So, I downloaded all the sources on the sources in
  ftp://mirror.cs.wisc.edu/pub/mirrors/ghost/gnu/gs550/ and
  http://prdownloads.sourceforge.net/hpinkjet/hpijs0.94.tar.gz and got
  this while compiling gs5.50:

    [wohler@gbr:803]$ make -f unix-gcc.mak prefix=/usr/local
    gcc `cat ./obj/cc.tr`  -O2 -Wall -Wcast-align -Wstrict-prototypes
        -Wwrite-strings -fno-common  -I. -I./obj -I. -I./obj  -o
        ./obj/zdevcal.o -c ./zdevcal.c 
    ./zdevcal.c: In function `calendar_get_params':
    ./zdevcal.c:53: storage size of `ltime' isn't known
    ./zdevcal.c:55: dereferencing pointer to incomplete type
    ./zdevcal.c:55: initializer element is not constant
    ./zdevcal.c:55: (near initialization for `items[0].offset')
    ...

  I probably won't pursue that path, but am curious why struct tm
  didn't get defined. After a few years of programming in Java, I have
  happily forgotten how to follow the spaghetti in /usr/include.

  I finally broke down and ran:

    [root@gbr:942]# dpkg --install --force-overwrite ghostscript-hpijs_5.50-2_i386.deb 

  gs --help shows the DJ9xx driver and it appears to work although I
  haven't noticed any difference in print quality for text. Ah, just
  printed a photo--there's the difference! (Possible to get my old 300
  dpi laser printer quality on the text on this 600 dpi OJ G85
  printer?)

  Another strange thing is that lprngtool doesn't show the new
  drivers... Any thoughts on why not?

  The example on the hpinkjet site explains that the duplex printing
  isn't working yet :-(.

I'm using gs 5.50a.  The cdj970 is an add on that slackware included. 
Sorry about that.  The filename is called gdevdj9.c.  I don't know where
slackware got it from.  I would be happy to send you that file, or a
compiled gs.

That looks like someone didn't include <time.h>, easy fix.

#include <time.h>, it was probably included in some other header on
someone elses system, but not yours.

Ah, so you got it.  Good.  So, the photos look better?

No, I just edit files by hand.

  Thanks for the feedback guys.

  Could you send me both please? That might tide me over until the
  hpinkjet folks provide for duplex. I'll look at the links David sent
  in a moment...

  Sounds reasonable.

> Ah, so you got it.  Good.  So, the photos look better?

  Yes! But I do miss the razor-sharp laser printer text quality.
