These problems have been fixed in version 1.0b3-1.1 for the current stable distribution (woody), in version 1.0b1-8.1 for the old stable distribution (potato) and in version 1.0b3-2 for the unstable distribution (sid). We recommend that you upgrade your html2ps package. wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
