I was shopping for a color laser printer and was considering an HP CP1215 with 16MB memory (nonupgradable)versus the CP1518 with 64MB memory. If the memory is insufficient does the printer print a partial page? Or refuse to print at all? Or gives a smaller gamut of colors with stepping (posterization) of gray scales?

The printer's internal memory is really just a buffer, which speeds things up on a network, but isn't really too significant if it is just used with a single PC. (or Mac) It won't have any effect on printing quality.

In my cases, if the internal memory can not handle a complicated page, you won't get the print out at all.

What software are you using? Many have defaults which rely on printer memory, but can be changed to stream the information to the pinter. There also may be settings in the printer driver which will allow printing of larger files than the buffer can handle.

I had an issue with the amount of printer memory when upgrading from Windows 3.0 to Windows 3.1. I was using Adobe Typeface Manager fonts prior to the upgrade, and Windows 3.1 had Microsoft Truetype Fonts instead.

After the Windows upgrade, thanks to Microsoft's new Truetype fonts, it was impossible for me to print in higher quality modes without printer out memory errors and partial pages with errors on complex documents (using Ami Pro at the time). Apparently, Microsoft's font implementation had greater printer memory requirements compared to Adobe's (and I was using a Panasonic KXP-4420 Laser printer at the time, which was HP Laserjet II compatible).

I then experienced the similar thing when trying to print a very high resolution picture using Preview.app (Mac OS X) to an Epson AcuLaser.

I have used color lasers in a network situation, but not run up against buffer limitations at (I believe) 32MB internal memory. I was not considering that, unlike inkjets, lasers need to contain the entire image in memory, due to the way they print. It still seems unlikely that the internal memory would be insufficient to print any document at the full resolution the printer is capable of. Of course, manufacturers (all of them) are notorious for promising more than they deliver.

Printer requires internal memory in printing operations. This post has lots of great information and inspiration.
