PostScript Support?

So I went ahead and got the retroprinter to connect to an ancient Sun workstation to enable PDF creation on printouts. After a whole lot of playing around with settings I couldn't get anything sensible out of it. Turns out it outputs postscript(?) which this doesn't seem to support? Are there any plans to support it or have I missed something?!

I did not realise that some computers / equipment would just print to postscript rather than HP PCL.
You should be able to overcome this by editing /home/pi/printpcl.sh (line 124):
Code: Select all
gpcl6 -dNOPAUSE -sDEVICE=pdfwrite -r720 -g$pageSize -sOutputFile="${outputDir}/${pdfPrefix}$(date +'%Y-%m-%d_%H%M%S').pdf" -sColorConversionStrategy=RGB "$filename";
Try replacing this with
Code: Select all
ps2pdf "$filename" "${outputDir}/${pdfPrefix}$(date +'%Y-%m-%d_%H%M%S').pdf";
This is untested at the moment. Add some captured sample files if I need to investigate please (as I don't have any postscript files).
I don't know if the -g$pageSize parameter could be used to stipulate the output page size

Thanks for the quick reply, I'll give it a go tomorrow when I'm back in work and let you know how it goes!

Hi again,
So I went ahead and made the change, originally it had some error where it’d create endless PDF’s from one printout. Checked the change I made and hadn’t capitalised something in the code. Changed that and now it doesn’t create any PDF’s.
Which files would you like me to upload?

Upload a sample postscript file (from /home/pi/data/raw/) and your printpcl.sh file - did you change it usingthe nano editor, or in Windows?
If you changed the script file in Windows, you may have inadvertantly changed the line endings!

Files attached, I did edit the file using the nano editor so line endings should be unchanged. 2 .raw files and the printpcl.sh attached

You will need to set /root/config/emulation
to
PS
(it is currently HP)

Hi again,
So I got the new version installed and set the emulation to PS, now it's creating blank PDFs? Was there anything else I needed to change and curious to know if you managed to create PDFs with the data and what they looked like?
Added files again incase they're needed
Cheers

I shall try this again here when I get a chance - did you restart the Retro-Printer after changing the emulation configuration ?
