Everyone, I have upgraded a RedHat 7.1 system to FC1 and have been gleaning many of the advantages; the biggest of which appears to be the processing speed seems much faster. However, I am still finding some differences that become hurdles. I finally got the printers working properly, but had to switch from the lp print command to the lpr print command. I have looked at the man pages and some web sites but could not find an explanation as to what the major differences might be between lp and lpr. I am using an HP4SI printer with the recommended hpijs driver. It seems that HP has written this driver for ink jet as well as Laser printers that use the PCL language. The problem I had was related to sending raw data to a PCL printer. On RH 7.1 I was sending a formatted file with the command 'cat filename | lp -d lpt1' which worked perfectly. When I tried to use this same command on FC1 all of the escapes of the PCL command sequences were filtered, and prevented from activating fonts and graphics on the printer. On FC1 I could not find a way to use the lp command to send a PCL file to the printer and had to change the command line to 'cat filename | lpr -P lpt1 -l' It's not a big deal for me to change all of the print commands to the new format, but I would like to understand more of what is happening with FC1. Most of what I will want to send to the printer will be PCL files. I would like some more information about the Linux print system as to what is CUPS actually doing to convert an unformatted file for printing to a PCL or postscript printer. Are their some links that can describe the differences between lp and lpr, or what kind of commands can be used to control font and graphic functions of the printer that will not be filtered but rather activated allowing the control of the printer. Thank you, Greg Ennis
