Snif the network between boxes during a print may tell you some things. Figure out the flow of data through the box that is hanging, and put in debug traces. So for example, stuff in some go-between scripts in /etc/printcap that print the time and such to a log. This can be tricky cause printing systems seem to be this huge kludge of grungy scripting pasted together with sticks and gum and duct tape, the syntax of printcap sucks, etc. So for example, cups may pass the data over to a rendering program at some point, eventually over to lpt, so try and put scripts inbetween these points and mark the time of completion: echo Step 1 at `date` >> /tmp/print.log Try to narrow it down to the troubled component. The basic flow should be something like this: printdata -> network -> lpd(cups) lpd(cups) -> /var/buffer(scripting hell) -> rendering if needed(more scripting hell) -> out to printer, wherever that may be. Sorry, I shouldn't make fun or call it scripting hell. Its actually the most incredibly flexible wonderful system, long live unix, printing standards, ra ra ra! STOP KILLING TREES! TIE YOURSELF TO A TREE WITH ROOTS YOU AIN'T GOIN NOWHERE. On Fri, Nov 14, 2003 at 01:09:37PM -0600, Robert P. Goldman wrote: > > Does anyone have any suggestions about debugging cups?
