The 16M SIMM will *NOT* work in the HP LJ4, but will work in the HP LJ4m+. The best you can do are three 8MB SIMM's.
I figured that, but there are lurkers, and people may find the tread in the future. :)

SUGGESTION: download a program like cutePDF (a free program that acts like a printer and creates a pdf file instead of actually printing it). THEN print the PDF. This gets you away from the postscript expansion problem that is choking your printer.
Yes it is:
When you send a print job to a PostScript printer, you're downloading a PostScript program which is interpreted, & as a side effect generates a bitmap which is dumped to the engine.
Yes, it does take up memory. This can be easily shown by running a PS test print on your PS printer. It will usually list how it's allocated the RAM.
IIRC, a 4M with PostScript maxes out at about 24MB of RAM. The printer has 4 SIMM slots, one of which is taken up with the PostScript ROM. I don't recall the default config for those printers, but I'd guess at
6-8MB. BTW, the symptom you get when you don't have enough memory is that when you send the file, the busy light/LCD will flash as though it's processing, then it'll go back online without actually printing anything.
What tends to happen to toner carts that're rarely used is that the toner 'cakes up'. The symptom is that the prints look weak & streaky, not unlike a nearly empty cart. You can usually fix it by taking out the cart & giving it a thorough shake to loosen up the toner.
I never wrote that! It consumes some of the address, but that's not the same thing as consuming RAM.
PostScript is a "programming language" only in the sense that it describes how to do something (ie, print a page). Try using it to write a compiler or an embedded application.
The PostScript SIMM takes up address space. But, PostScript
*itself* uses RAM to keep track of what it is doing. Just like a BASIC interpreter can reside in ROM (on the early IBM XT, for example) yet still require RAM to run the programs it is fed.I posted a PostScript PROGRAM that computes pi. To thousands of decimal places. You *could* write a compiler in PostScript.
From wikipedia (*first* sentence of each topic):
POSTSCRIPT: "PostScript (PS) is a dynamically typed concatenative programming language created by John Warnock and Charles Geschke in 1982."
BASIC: "In computer programming, BASIC (an acronym for Beginner's All-purpose Symbolic Instruction Code[1]) is a family of high-level programming languages."
COBOL: "COBOL (pronounced /?ko?b?l/) is one of the oldest programming languages."
PL/1: "PL/I is an imperative computer programming language designed for scientific, engineering, and business applications."
FORTRAN: "Fortran (previously FORTRAN) is a general-purpose, procedural, imperative programming language that is especially suited to numeric computation and scientific computing."
ALGOL: "ALGOL (short for ALGOrithmic Language) is a family of imperative computer programming languages originally developed in the mid 1950s which greatly influenced many other languages and became the de facto way algorithms were described in textbooks and academic works for almost the next 30 years."
C: "C is a general-purpose computer programming language developed in
1972 by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system."C++: "C++ (pronounced "See plus plus") is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language."
ML: "ML is a general-purpose functional programming language developed by Robin Milner and others in the late 1970s at the University of Edinburgh, whose syntax is inspired by ISWIM."
Python: "Python is a general-purpose high-level programming language."
Perl: "Perl is a high-level, general-purpose, interpreted, dynamic programming language."
SNOBOL: "SNOBOL (String Oriented Symbolic Language) is a computer programming language developed between 1962 and 1967 at AT&T Bell Laboratories by David J. Farber, Ralph E. Griswold and Ivan P. Polonsky."
Lua: "In computing, Lua is a lightweight, reflective, imperative and functional programming language, designed as a scripting language with extensible semantics as a primary goal."
(ad nauseum)
Do you claim that none of these other PROGRAMMING LANGUAGES are
*not* programming languages? Then why do you claim PostScript isn't?Spend some time *reading* a PostScript *program* and you will see that it's much different than PCL5 output. It actually
*computes*. Download a copy of GhostScript and "talk to it". Once you have tried this, it should be fairly obvious that you could write a PostScript program and *interact* with it under GhostScript.Here's more examples (clip and send to your PS printer). I previously posted a program to *compute* pi. The first *computes* the date on which Easter Sunday will fall. The second generates the verses to "99 bottles of beer on the wall". The third one is a WEB SERVER written in PostScript! [Credits to each of their individual authors]
Gee, they *claim* its a programming language and it sure
*behaves* like one! :>----------8
