The Question is: I have some very specific text only (not Post-script) files that are only half printed to a HP Laserjet5Si printer, before the printer suddenly starts interpreting the job as postscript and then fails because, of course, the data trying to be interpretted as postscript simply isn't. This does not occur on every file - about 1 in 10,000 perhaps, which happen to contain many lines starting with a '%' character. I can force a correct printout of such files by sending the escape codes to the printer to force PCL rather than Postscript by adding them to the top and bottom of the file (Esc%-12345X@PJL LANGUAGE = PCL and Esc%-12345X). However, when I add these escape codes to the existing modules (including the 'RESET' module)in the system library the printer uses, they are ignored. I have even enclosed these escape codes within a 'EscP' and 'Esc\' as otherwise I have read that these codes are interpretted 'incorrectly' by OpenVMS (being non-ANSI) leading to a blank page before the print out starts. We are using LAT as the network protocol for printing. We have no requirement for Postscript printing from OpenVMS. Is there any way I can successfully force these HP escape codes to the printer to force non-Postscript mode using HP's escape codes with modules in a system library? Other such codes in these modules are interpretted correctly (e.g. portrait, landscape etc). Many thanks. The Answer is : This does not appear to be an OpenVMS problem, this appears specific to the particular printer involved and its interpretation of the data being received. Please contact the printer vendor for assistance and configuration options, and for information on the current firmware revision and for details of how the file format determination is made (assuming the printer is attempting to sense the format). If this is a problem with autosensing within the printer, you are left to seek the assistance of the printer vendor, or send data that will not trigger the Postscript interpreter, or to prefix the file with text from (say) the device control library or with a request for the standard print header text (and thus get text other than the existing text containing the percent signs to the top of the file).
