After a long delay, I have found a little time to investigate further. If I create two text files test1.txt and test2.txt containing the single words ONE and TWO respectively, then the problem does not occur if I print them in sequence:
lpr test1.txt ; lpr test2.txt If I convert them to postscript using enscript: enscript -p test1.ps test1.txt and likewise for test2.ps and use lpr test1.ps; lpr test2.ps then the error shows up. The first test1.ps is printed correctly, but the second is not: it prints the usual PJL commands. Maybe the PCL stream for test1.ps is not terminated properly, or the UEL "<esc>%-12345X" is somehow corrupted. I see a #define UEL "\033%-12345X" in ghostscript-6.30-hl1250-patch-0.3.gz. But that patch is 14 years old and I have used ghostscript directly with the hl1250 before using cups with no problems. I intend to experiment with the current ghostscript to see if the problem shows up there. But I need to refresh my mind about raw postscript first. Meanwhile I am attempting to capture the raw data sent to the printer as described in https://wiki.ubuntu.com/DebuggingPrintingProblems. However I am having trouble getting the output into a file. lpadmin -p test -v file:/tmp/printout ... does not seem to create the /tmp/printout. I tried -v file:///tmp/printout after consulting the lpadmin man page. The print jobs succeed, but no such file is created and so far I can't find where the output has gone... The http://localhost:631/ interface shows a "Connection: file:///tmp/printout" or file:/tmp/printout in each case and shows the test jobs as complete. This is just an interim report. Until I solve the print-to-file configuration, I don't think that I will make much progress.
