Hello,
With the existing (and added in our CUPS installation) FreeFonts, we are printing happy UTF-8 text files (even if there are still missing a lot of glyphs and the subject in general needs more attention in the future);
one problem is showing up in production environment:
the resulting Postscript output which is sent to the printer is because of the embedded FreeFonts around 1 Mbyte for a simple text page and the printer has to interprete this bunch of data; it takes on a normal HP Laserjet 205 seconds for 10 print jobs of each 1 MByte data, i.e. an average of 20 secs for a page;
I tested the following:
1. used texttops to convert the UTF-8 text to Postscript as shown above
2. convert the Postscript file to PCL with:
gs -dBATCH -dNOPAUSE -sDEVICE=ljet4 -sOutputFile=file.pcl -sPAPERSIZE=a4 file.ps
3. print the resulting PCL file with -o raw via CUPS;
the result is promising:
- the file is only 200 KByte for a page
- it takes 55 secs to print 10 files
Comments?
Is there some work in progress to integrate CUPS and Ghostscript in that way?
Thanks
matthias
