Printing Kudos and a question

Hi the to printing group. I just bought a HP DeskJet 950C printer. This is
SUPPOSED TO BE a near photo quality printer. I was disappointed to see the
results under Windows with the HP driver that came wiht the printer.
Apparently, if you don’t have 4 GB of RAM the driver can’t do it’s best to
print in photo quality mode.

But much more disappointing was that it took forever (1 hour and 45 minutes)
to print a full page photograph. I bought this printer to print photographs
but I can’t use it if it is that slow.

So, I tried it under Photon. I was very impressed that it was VERY fast. I
was printing at 300x300 and I tried QNX dithering, Error diffusion and
Halftone printing. They were all very fast.

So now here’s the question. Now of them were near photo quality. How can I
improve the print quality. Can I go above 300x300? I have photo editing
software that can do anythin with the image.

Also, how do I tell pv to print exactly the pixels in the image? I don’t
want it to expand the image. If I am printing 300x300 dpi and I print an
image that is 1200x900 pixels I expect it to be exactly 4" x 3".

Hi Bill,

I have spoken with one of the developers and you could try editting the
/etc/printers/pcl.cfg file and add a higher resolution to it.

Let me know if it works.

Brenda

Hi. I formatted my image to 600x600 and saved it as a BMP. I then added a
600x600 option to the pcl.cfg file. I then loaded the image with PV. I
looked great.

I went to print the image. I went into properties and selected the 600x600
option. I then tried to print the image. The printer light started
flashing (which means that it did receive some data) but then nothing.
After just 1 second there was no CPU load. And there was no new data going
to the printer.

Good for you Bill; personally, I’m not very photogenic :slight_smile:

Hi Bill,

Could you try printing the following way?
That is:

  1. Open the BMP in pv.
  2. Print the BMP to a PHS file.
  3. Run the printer filter manually from the command line, e.g.,
    $ phs-to-pcl -or600 print1.phs > /dev/par1
    (assuming your printer is attached to /dev/par1)

Also can you tell me the file sizes of the BMP and PHS files.
Thanks.
Brenda

The output to the .phs file was 224 bytes. I’m guessing that that is not a
valid file. Or you folks have found one hell of a compression algorithm.
My bmp file is about 2 MB. A jpg of the same image is about 700 kb and
produces the same 224 byte phs file. At least your consistant.
