is my teachers statement correct?

[lockmac]

Hey. My IPM teacher is telling us that bubble jet printers are better in the sense that they use the memory of the comptuer and hence can print larger documents, whereas laser printers rely on their own memory. I know that this is true in the sense that typically, laser printers have their own memory but is she completely correc tin saying that ALL bubble jets use the PC memory and ALL laser jets use their own memory?

Thanks

I don't know if all lasers use there own memory, but the good ones do. But your teacher is nuts, lasers are far and away better than inkjet printers by any measure. Mine has 12 megs of ram that I got free, and it never runs out of memory. The print quality after 3 years of use is still as good as the day I got it, and the cost per page is next to nothing. Inkjets always get pluged, or loaded up with old ink. And buying ink at three bucks a drop makes me insane. When my printer only had 2 megs of ram, windows still spooled everything that wouldn't fit in printer memory.
You need a new teacher.

What your teachers says is party true. It doesn't make Inkjets better, it just makes them depend on the host computer. One reason they are so cheap is they lack the processing and ram features that laser printers usually have. The computer then does the processing.

I don't know if this is universally true, but if it isn't, it's close enough to say it is. Laser printers do in fact require the entire page to be in local memory before it can start printing, that includes all necessary fonts, graphics, etc. This means you may suffer degraded (dithering) print quality with graphics if they don't all fit into memory. For typical tasks, this should never be any issue with any B/W laser printer having more than 8MB of RAM or so, but your teacher is correct that laser printers do have memory limitations, while ink jets don't allowing them to print out larger documents.

Not true.

Ink jet printers for the consumers do as he says. Laser printers for consumers do what he says as well. Both have on board memory, lasers typically have more or actually advertise it. Lasers still cost more than inkjets cuz lasers inherently require MORE material to make, more parts, etc. cuz of the necessary size.

Business\enterprise class inkjets and lasers both have high amounts of memory and processors.

The only time I've found this to be an issue with my laser jet is when I'm telling it to print pdfs as images, which is pretty rare. With regular documents, it's a non-issue (the printer can't physically print fast enough to run out of memory), and having a toner drum that has enough juice to print 5000+ pages is a nice plus.

what is "IPM"?

and as far as the memory, you can usually add more memory if needed to a laser. as others stated when you get into the large format printers, then they all have cpus and memories.

Your teacher was inaccurate. Although it is true a laser requires a whole page to be within its memory before it starts printing it can also use the system memory to cue or spool the remaining pages of the print job. Sure it will slow it down and same with the system depending on the amount of memory available. I've got an old laser with only 2MB of memory but not once did it stopped me from printing an entire book. Although, I will agree it took longer.

Gotta love all thee poeple commenting on things they havce no clue as to what the issue is!
Only in a forum like this would Junior High School kids dare call an teacher who most likely has at least there 4 year college degree an idiot or wrong....

Also its pretty sad when somebody makes a post like this asking people any people that is whether they have actual knowlwdge of facts to comment on what a teacher has stated,

Not to demean those posts that did`nt say anything at all about what the teacher said.

Too funny.....you can`t beat this for entertainment value!! rofl

what does the teacher have their degree in? wtf is is IPM anyway?

 

[LTC8K6]

My new HP Deskjet 6122 and old 932 inkjets both have 8MB of ram.

JEDIYoda, you bought a P4 3.2 extreme, which just about disqualifies you from this entire board. :beer:

You didn't happen to be the teacher in question are you?

A laser printer MUST copy the entire page into its memory, it has to 'lay out the image' before flashing onto the drum. Bubble Jets don't need to do this. Now to add a little extra. The memory size of the laser has nothing to do with the size of the document. The issue is the complexity of the pages in the document. Graphical images with a high density or resolution are the ones which cause the problems for the laser. I would never use the term 'better or worse'. Each printer has its own benefits and issues. (BTW technically the laser printer does not need to have its own memory, the image could be laid out in the PC memory, if a high speed interface allowed for the transfer of the data to the printer as needed, it would be integrated into the PC).

applicable adage/oldie-but-a-goodie: Those who can, do and those who can't, teach. - anyone who's a supposed "expert" in IT that chooses to be an instructor at a local college and make relative peanuts compared to their earning potential in the "real world" is either a saint or an idiot. - In my 4 years at the University level I never met a saint.

While technically the prof is correct, the notion that bubble-jet printers are anywhere near comparable to laser printers in any category is absurd. - Is this an A+ class or something?

so does this mean my colour laser would need a hell of a lot more memory than a comparable B/W?.....Me got 40Mb.....never had any probs and as someone said earlier the toners last ages! bubblejets just can't compete with the quality......laser printers are getting cheaper all the time too!

Dell Laser Printer 3100cn Review

"Its photo quality is potentially better than our rating. The base unit does not include enough memory to print our 8- by 10-inch photos at the highest quality setting, and that forced us to use a lower quality mode. According to Dell, the 3100cn could have printed our test files with a $60 memory upgrade, to 192MB."

The base memory for this printer is 64MB, which isn't a trivial amount. This is a problem that would not surface when using an inkjet printer and what the instructor was alluding to.
