I think that what Mike is trying to say is that if you were to go to the HP website and call up a document titled "HP LaserJet printers - PCL Commands, Basic Page Formatting, and Font Selection" you would look though this and see under the Paper Source, length, and size section that the escape code for selecting A4 paper is Ec&l26A Then, if you were to go to my book, or failing access to a copy of it, go to http://www.freebsd.org/doc/en_US.ISO_8859-1/books/corp-net-guide/index.html and click on 8.7.4 Filters, then if you scrolled down a bit you would see a printcap filter in a section saying: "Here is an example of a filter that triggers the printers automatic LF-to-CR/LF converter (this option is only useful on HP LaserJets that support this command): #!/bin/sh # Simply copies stdin to stdout. Ignores all filter # arguments. # Tells printer to treat LF as CR+LF. Writes a form feed # character after printing job. printf "\033&k2G" && cat && printf "\f" && exit 0 exit 2 You might then proceed to replace the \033&k2G with the \033&l26A and install the filter per the instructions in the rest of the chapter (which I strongly suggest you read) and if your Laserjet is smart enough to know that it has A4 paper installed in a tray, that you just might find it work the way you want. Keep in mind, though, that only some HP Laserjets can detect what type of paper they have, and also they do this by sensing the tray used. For example, in a HP LaserJet 4+, if your tray is a Letter tray, you cannot stuff A4 paper in there, the printer will still think that it's Letter sized paper. You must purchase the A4 tay for that. For example, in the HP5SI, the trays have some plastic barriers that need to be rearrainged and a twisty knob that needs to be changed to select A4. Like Mike says, there's other useful codes in that HP document, for example you can change the font size t be very small, turn on or off duplexing, change portrait or landscape, and so forth. You can combine codes to have multiple things happen at once. Also, of course, this only works in PCL mode, if you transmit a Postscript job then these filters won't do anything (or could cause problems). For example, printing from Netscape running under X windows, you get Postscript code from that application. This is only going to be useful for text jobs sent to the printer.
