However, I find 600dpi much more beautiful than 300dpi. Therefore I use the printer at 600dpi, which costs app. 4 times as memory as 300dpi does. Furthermore, I presume that at least Windows uses the fonts that are built into the printer which is economical. Standard LaTeX however, uploads it own fonts to the printer and this adds to the memory consumption of course.

The printer will be unable to print *pages* which pixels (as provided by Ghostscript) will not fit in memory. If you have 10 pages, each needing about 600k, you only need 600k for printing them as the pages are discarded from memory as soon they are printed. I suggest you purchase an additional 4MB JEIDA memory expansion card (about DM 100 = $ 56), don't buy the original from HP as it is much more expansive. They are also available with 1MB, 2MB, and 8MB in size. When I had the original 1 MB memory in my Laserjet 5L (very similiar to your model) I had problems printing some pages with a lot of text (e.g. a2ps double-sided), the printer was unable to compress this information to fit in 1 MB and left out some pixel (it did not even switched to 300dpi). The additional memory will also allow you to use download-fonts (is this supported by ghostscript?) and buffer some pages.

True enough, no doubt. But please note that what I wrote was intended to be read in two parts: one about RAM requirements for PostScript printers proper, the other about printing PS to non-PS printers for which a pre-converter (e.g. ghostscript, raw or as wrapped in ghostview) is required. In the latter case, the printer's RAM for native printer code (e.g. PCL) should be adequate for a page at a time. Ben's comments confirm this for the 5L. With PS printers, on the other hand, it's a different story since PS is a fully-fledged programming language which is quite capable of piling very large chunks of data onto stacks. Hence the need to be alert to RAM demands in this case. Is there not a version of the 5L which can be obtained with a true PostScript option installed? Best wishes, Ted.

Re: Memory and printing
Though everything that Ted says is true, I must note that an HP 6L is not a PostScript printer. I have a 5L at home with 1 MB memory and can say that, under PCL, that that is enough memory to printer anything but the most complex graphics at 600 dpi and I haven't found a page yet that failed to print at 300 dpi.

For a page consisting mainly of text which only calls for the fonts that come with the printer, the page requirement is only a few KB and there's no problem. If you have graphics, or if you're downloading the font definitions on the fly (as with TeX), then there are much greater demands on printer memory. If you have a lot of graphics, then almost certainly 1MB is not enough. 2MB is probably enough most of the time but may sometimes be inadequate. 4MB is almost certainly adequate. As a general rule, you can print PS files which are overall very big, provided you don't exceed the printer's RAM for each page. On the other hand, you can print PS on a non-PS printer provided you run a PostScript->whatever interpreter on your conputer: this generates native printer code, and all that is needed is that the printer can accomodate whatever native code is required for each page (as it should, or take it back). The computer can carry the burden of composing the page before sending the native code to the printer. One possibility is ghostscript, but this tends to suffer from font-rendering problems and can give disappointing results if you need good-looking hard copy. Hope this helps, Ted.

Memory and printing
Hi, I am thinking of bying a laser printer but I have one question. I will be printing some large documents with lots of graphics in them. The files will have the postscript format. For example one file I recently printed was 6.2 Mb. The cheapest laser printer is HP 6L with 1 Mb of memory. Does this mean I will not be able to print my files which are larger than 1 Mb? Or doesn't it matter as long as my computer memory is large enough ? Any hint will be appreciated.
