discount hp printer memory upgradeInstalling more printer memory offers many benefits,  including:

  • Increased speed on PC
  • Faster printing
  • Print larger files
  • Allow for application processing to run faster
  • Increased overall productivity

Added printer memory shows dramatic performance improvements with spreadsheets, slide sets, desktop publishing, and web printing.

Modern laser printers are actually very specialized computers with their own processor, memory, I/O and network connections, and even some with their own hard drives. These printers are often also expensive, costing as much as a complete PC or Mac computer system. For this reason, users want their printers to last several years before replacing them and therefore need to upgrade their printer in order to keep pace with growing printing needs.

Why Upgrade?
When a print job is sent to the printer, the data and formatting codes are loaded into the printer's memory, processed and printed. Without enough memory available in the printer, the process can slow down, can cause the printer to refuse to print the document or even lock up your system while it is sending the rest of the document.

Benefits of Upgrading
When you add memory to a printer, you increase printing capabilities in a number of ways. One benefit is increasing the number and size of documents stored in the printer's memory; which is very important if the printer is being shared on a network by many users. You will also be able to increase the complexity of graphics files handled by the printer, and have the ability to print on legal or ledger size paper or to print at higher resolutions which is required by certain laser printers. Upgrading your printer basically free up the memory resources of the computer sending the print job, so the document can be processed quicker and you can get back to doing other things.

In the past, printer manufacturers used proprietary memory designs, but now, most of the top manufacturers are using standard memory modules. This makes upgrading printer memory cheaper and easier. However, some manufacturers of today's printer memory, such as HP, require that 70ns SIMMs be used in their printers.

Select your right HP Printer Memory

What are SIMMs?

Many HP printers take 72-pin SIMMs ("PS/2" SIMMs).

What does that mean?

This depends on the kind of printer you have. Some need SIMMs with parity, some can take SIMMs with or without parity (SIMMs w/o parity are a lot cheaper).

HP LaserJet IIISi, 4(M), 4Si(MX), DJ 1200C(/PS), PJ XL300(/PS), DnJ A/B, DnJ 200/220 and DnJ 600 printers:

  • The SIMM needs parity. Real parity, not "fake" (computed) parity.
  • The SIMM needs to be FPM, 70ns or faster. EDO memory will work in some printers, but not all.
  • The Presence Detect pads need to be connected correctly.
  • N.B.: HP's part numbers for parity SIMMs are C2065A and C2066A (4MB and 8MB respectively).

Almost all other HP models that take SIMM:

  • The SIMM does not need parity.
  • The SIMM needs to be FPM, 70ns or faster. EDO memory will work in some printers, but not all.
  • The Presence Detect pads need to be connected correctly.
  • N.B.: HP's part numbers for non-parity SIMMs are C3132A, C3133A and C3146A (4MB, 8MB and 16MB respectively). There seem to be several part numbers for 32MB SIMM, I have seen D2298A, D3578A and KTH-NPVEC/32.

Memory types?

FPM stands for "Fast Page Memory". This is an old memory type, usually found at 70ns or 80ns. Anything 60ns or faster stands a good chance of being EDO, though there is 60ns FPM memory. You cannot tell FPM and EDO memory apart by just looking at the module; though you can look up the part number of the memory chips used and see whether they are FPM or EDO memory.

To tell memory with parity apart from memory without parity, simply count the number of memory chips on the module. If it has 9 or 18 memory chips, all alike, it has parity. If it has 4 or 8 or 16 memory chips, all alike, it does not have parity.
If your module has 8/16 (unlikely to be 4) memory chips and then another 1/2 chips that are not memory (but probably "in line" with the memory chips, like this: MMMMcMMMM), then it most likely has computed parity rather than real parity and will not work in a printer that needs parity.
What looks like a parity module might also be ECC, though; so be sure what you are getting before you get it.

Regarding EDO SIMMs: Whether this works depends on your printer model. Seriously though, we have had reports of successful use, and reports of unsuccessful use.
The memory controller has to support EDO if there is to be any chance of it working. With older printer models, that is probably not the case.
Mixing FPM and EDO is discouraged, because it is not stable at what was considered high memory access speed in those days. However, since HP says "80ns or slower", we do not necessarily see a problem in using EDO, as long as it works: Even though the built-in memory will be FPM, and thus you are mixing.

ECC memory is error-correcting memory and will never work in a HP printer, though it will physically fit.

Regarding speed: 70ns or faster means you can take a 60ns SIMM, encode it as 70ns, and it will work. We have successfully done this. HP actually quotes 80ns, or "80ns or slower", but we like to be very conservative about this kind of thing. SIMMs you buy nowadays will be 60ns, anyway.

Presence Detect pads?

Right. Pads (or pins, if you so will) 67 to 70 on a 72-pin SIMM encode the size and speed of that SIMM. Each of them can either be open or connected to GND (ground). Look at a SIMM you took out of your PC. Chances are you will see traces running from pads 67 to 70 to empty points where a solder blob or SMD resistor would fit. If the traces run to actual solder blobs or zero ohm SMD resistors, then the SIMM has been encoded already ... it just remains to be found out whether it has been encoded correctly.

PC clones, as a rule, do not use the Presence Detect pads on a SIMM. That's why the pads are (usually) left unsoldered. Furthermore, there is no standard for the encoding of these pads. IBM has their own way, as does HP, as does Dell, as do others.

So the printer recognizes memory just by the pattern on these pads?

Exactly. If all four pads are open (no solder blobs, no resistors), then the printer will not "see" the extra RAM ... it's as if you never put that SIMM in there. Once you put some solder over the right points on the SIMM, you have magically transformed a $39 SIMM into a $150+ HP printer memory expansion.

Personal Printing

Test of Hewlett Packard LaserJet 1100 series printers with added RAM memory show these dramatic performance improvements with spreadsheets, slide sets, desktop publishing, and web printing:

  • Adding 4MB of DRAM for a total of 6 MB reduces output times by 30 to 80 percent
  • Adding 10MB of DRAM for a total of 12MB virtually ensures no "memory out" errors

Hewlett Packard LaserJet 2100 series printers require 20 MB total to print multi page 1200 dpi documents with comparable performance 600 dpi documents.  Examples using 20 MB:

  • Output time reduced by 66% with a 10-page slide set
  • Output time reduced by 33% with a 5-page report
  • Output time reduced by 66% with a 10-page HTML file
Shared Monochrome Printing

Tests using Hewlett Packard LaserJet 4000, 5000, and 8000 series printers show a range of performance improvements when base RAM is supplemented.  Users should consider adding RAM if they frequently print the following:

  • Multiple-copy slide sets - print time reduced more than 50% by upgrading to 36 MB
  • Web-based HTML files- print times reduced by 30% by upgrading to 20 MB
  • PDF files - print times reduced by 50% and errors avoided by upgrading to 24 MB
  • Multi page general office documents - print times reduced by more than 50% by upgrading to 20 MB
Color Printing

RAM is especially critical to reducing print times of color files.  Tests of Hewlett Packard Color LaserJet 4500 and 8500 series printers showed that increased RAM would improve performance in these categories:

  • General Office - print-time reduction is 30% and errors is eliminated with 48 MB
  • Color Presentations - Print-time reduction is 40% with a total of 64 MB; with two-sided documents, an additional 16% performance improvement is achieved with 96 MB
  • Graphics-Rich Files - when testing vector drawings and TIFF images, print times for large 8 by 10 inch images decrease by 24% with a total of 56 MB
  • Desktop Publishing - print-time reduction is 30% is achieved with a total of 96 MB
