What program you print from? I'm printing from KDE. The 370Kb image was printed from Konqueror.
What kind of printer you have? It's an HP LaserJet 5MP, it's an PostScript 2 printer
How is it setup? I just configure CUPS with 2 queues : one as a raw printer, no filtering, and another as an HP LaserJet 5MP with the manufacture PPD.
-- Regards, Lívio Cipriano I print the SELF TEST of my printer and I notice that has:
Installed Personalities: PCL (94110823) POSTSCRIPT (95040353)
So, I just configured my HP LaserJet 5MP as an PCL Printer, and the improvements in the printing speed of graphics were immediately. An image of 370Kb that yesterday took 15-20 min to print, now took 1-2 mins. Any explanation?
It looks like your printer does not have enough memory to handle the postscript file. The pcl version requires your computer to process the file and generate an image of the page, translate it to pcl, then send it to the printer where there is little processing.
In postscript, it sends a postscript file (program), the printer executes the program, draws the image, then prints the files. Typically if you have a complex image and very little memory, it takes a long time.
Historically Postscript always has been rather inefficient at processing bitmap images. Generating rather large ASCII representations of the binary image info. If remember correctly PCL does represent binary as binary, resulting in much smaller filesizes. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iD8DBQFGYYj0asN0sSnLmgIRApDUAJ9fR345J/o8PY9Uaa/GqNjU1CZZ9gCdEu9J fMmh8WXGuE0EoEL7aKyrIa8= =1Zhe -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
