Printer Connection</H1 ><P > Prepare Linux/IrDA as described above. Especially check for the existence of <TT CLASS="filename" >/dev/irlpt*</TT > (if it doesn't exists do as root <B CLASS="command" >mknod /dev/irlpt0 c 161 16</B >). Now you may perform a first and simple test. Try to write a small file to <TT CLASS="filename" >/dev/irlpt0</TT > by <B CLASS="command" >cat FILE >/dev/irlpt0</B >. Do not wonder about a bad format (the lines form sort of steps) this is just a first check. If this doesn't work please check the permissions of <TT CLASS="filename" >/dev/irlpt0</TT >. Watch whether the connection indicator of your printer shows activity, e.g. the green light above the InfraRed port of a HP 6P/MP comes on (lower left hand corner, near the paper tray). </P ><P > The <B CLASS="command" >cat</B > command will not produce formatted output, but is useful for testing. If it works, you may set up an IrDA capable printer depending on your printer system. See the documentation, e.g. the Printing-HOWTO from <A HREF="http://www.linuxprinting.org" TARGET="_top" >LinuxPrinting.org</A > for detailed information. </P ><P > With the <A HREF="http://www.cups.org" TARGET="_top" >Common Unix Printing System - CUPS</A > use for example with a HP LaserJet 2100: <TABLE BORDER="0" BGCOLOR="#E0E0E0" WIDTH="100%" ><TR ><TD ><FONT COLOR="#000000" ><PRE CLASS="programlisting" > lpadmin -p IRDA_PRINTER_NAME -v parallel:/dev/irlpt0 -E -m de/hp2100_6.ppd.gz </PRE ></FONT ></TD ></TR ></TABLE > To get a list of paths to your ppd files use <B CLASS="command" >lpinfo -m</B >. </P ><P > Of course other printing systems will also work, e.g. you may edit <TT CLASS="filename" >/etc/printcap</TT > and include <TT CLASS="filename" >irlpt0</TT > as the printer device. </P ><P > The better way is to change your <TT CLASS="filename" >/etc/printcap</TT > to use <TT CLASS="filename" >/dev/irlpt0</TT > in addition or instead of <TT CLASS="filename" >/dev/lp1</TT >. </P ><P > For easy printer setup you may use a printing software like APSFILTER, MagicFilter EZ-Magic (with RedHat there should also be a GUI for this purpose). Make a copy of <TT CLASS="filename" >/etc/printcap</TT > before. </P ><P > Example for APSFILTER with a HP 6P (non-postscript, HP 6MP is with postscript). The two relevant questions are: "Do you have a (s)serial or a (p)arallel printer interface?" Answer "p" "What's the device name for your parallel printer interface?" Answer "/dev/irlpt0" </P ><P > Restart the print daemon with <B CLASS="command" >kill -HUP <PID of lpd></B >. If you use another print daemon choose the according command. </P ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="infrared-howto-s-low-level-drivers.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="infrared-howto-s-lan-connection.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >Starting the IrDA Stack</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="infrared-howto-c-specific-connections.html" ACCESSKEY="U" >Up</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >LAN Connection - IrLAN</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
