Printing issues

Hello All, I am having mixed results printing on a Debian Stretch 64 bit system with a HP LJ4+. I can print postscript from the command line, I can get the test page to print, but nothing from LibreOffice 5 nor a text editor such as leafpad. There is some data sent to the printer, but it just sits there and taking off line and pressing the form feed does not produce a page, even a partial page of something. Adding to the insult, I cannot set it up as a second printer, but non-postscript. I am far from impressed, it is now an unduly complicated mix of bits and pieces that is difficult to follow and sort and read to see the configuration and understand to debug. Regards, Mark Trickett
