Well I got it working.  I am not sure how.  I can't remember doing anything different from what I did before.  Plugging in the USB to parallel cable (Campture2.jpg)  automatically showed up in the printer output port (Captured001.jpg).  I then reinstalled the HP 2100 printer and driver.  Sending a print job to the 2100 printer starts the light on the printer flashing.  NOW - let me report that is is working but ever so slowly.  It took 25 minutes to send down and print four (4) lines of simple text.  We are talking about 250-300 characters.  It takes hours to send down (print) a single page of rather full pdf info.  Yes it does work but not what I would call useful work.

Yep, ArcaOS 5.1.  Yep, the hp 2100 laserjet has a parallel connection only.
Installed the legacy HP 2100 laserjet driver.  And directed the output to the USB to parallel cable USB output port ('Prolific_IEEE_1284_Cont_1').
Works great with the old laptop that has a parallel port (LPT1) with the legacy driver.
I did try a shorter cable.  That was how I got the error message.

Later I thought to try printing a simple text file instead of a DeScribe file.  After a few clicks on the 'ignore' printer warning window the printer printed:
PCL XL error   Subsystem: IMAGE    Error: ExtraData     Operator: ReadImage     Position: 37

Thanks for the ideas.  I will see how much time I will have to spend on this with classes starting.  Maybe I will try under Windoze in an attempt to test the cable.  But since I don't know Windoze very well it will also be a challenge.

I went with a Ugreen USB to DB25 parallel printer adapter cable since I have a very long parallel cable running around the edge of my office.  When I plugged in the USB to my laptop, OS/2 reported a Prolific_IEEE_1284_Cont_1 in the Printer Outout Port tab.  Yea.  But, that didn't work.  I wondered if the problem might be too long of a parallel cable so I tried an old (very thick) parallel cable.  Still to results.  After trying to print and a timed out from the OS the printer spits out the following:
PCL XL error
   Subsystem:  KERNEL
   Error:   IllegalOperatorSequence
   Operator:  BeginFontHeader
   Position: 28

I also tried using printer only fonts but no output from the printer this time at all.

I wondered if I should set the numbers on the USB port Printer -> Properties -> Output Port -> (#2 click ->) Properties -> Timeouts in seconds (Print, Query, Job) any differently?  Or any changes in the Advanced Properties?

Thanks for any ideas.

HP laserjet 2100 located in my office at work (University) so I have to stay local (USB, was parallel cable).  At home I put an HP color laserjet on the home network.  It runs great even with the incorrect old (included) driver.
Thanks, ME

New laptop (notebook).  Has anyone had any success connecting a parallel printer to a USB port?  I have a cable.  Do I need a driver?  If so where do I find said driver?

Thanks,

Sorry no problems here.  Running fine under ArcaOS.  But I did install the program some time ago.  Also I am using the old (original) file open container.

Yep.  I am getting there.  OpenOffice will export each slide as a jpeg using the export as html.  This also gives me the option of simply setting up the slides on a web server.  All I have to do is generate an audio file for each jpeg then add one line of code in the html file and good to go.

To get the timing right on a mpeg4 video, I am thinking of using AVxCAT to generat a mp4 of each slide which would be the length of the audio file.  Then combine the mp4s into one file using AVxCAT.  That gets around timing the audio to the default specified time for each slide.

I am hopeful.  Now to record the audios, where is that mic that came with OS/2 back in the 90s?
Thanks for the help.  I will continue to update.

I was after, some work (that was a challenge for me) got AVxCAT and ffmpeg 4.0.2 running.  It looks like I have to create an audio file first then attache it to the slideshow.

Problem: Following the directions for AVxCAT I can't get the Validate button on the advanced screen to activate (unshadow).  I may be missing something in the Video stream: dialog box.  But my screen (unlike the screen shot in the help) never shows the slider bars for first frame(s): and last frame(s):.  So maybe something is wrong with my install.

Question:  What software do you suggest to make an audio file?

Working hard,
Mike

With all university classes going all online I would like a suggestion.  Is there any OS/2 software I could use to create a file (?mp4?) that shows slides (OpenOffice) with voice overs?  I want to create a lecture that students can see the figures (molecular biology) and hear me explain the figures.  I want to then upload the file to the university server.

Thanks,
