You could get the PostScript DIMM for the 2100 and eliminate apsfilter. The speed increase would depend on what type of things you're printing, but it's inexpensive (saw the DIMM on printerworks.com for $39). -Warren Block * Rapid City, South Dakota USA ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

One additional piece of data: on my USB1.1-connected Epson s-C82 under CUPS: Every six or eight passes the printer pauses. During this interval, the computer's CPU usage spikes. It looks as though there is some critical place without needed double bufferring. I don't know what this might do to a laser printer, which needs to have room to stop and start, and may hold data back if it sees that a stop is soon likely.

Yes I also have the impression that it has something to do with the translation from PostScript to PCL. The printer prints 10ppm from my laptop with Windows2000, so it can't be a hardware problem. I think it has to be a driver issue, some difference of printing systems between FreeBSD/Windows. > also take a look at (misleadingly-named) www.linuxprinting.org.

The printer is connected to a small network at home, three computers all running FreeBSD and the printer, all connected to a switch. Sometimes I plug a laptop from my work into the network, which runs Windows 2000. Now I think that the data sent to the printer is PostScript and not PCL (if this is possible, I'm no expert on this but I guess that's the reason Windows is printing a lot faster) and that I should install a so called "PostScript emulator DIMM". Problem is that these are hard to find since the LaserJet 2100 is an old model now. I just got a tip on the mailinglist that they are still being sold at http://www.printerworks.com.

I'm wondering if the problem is that everything going through APSFILTER is sent as Postscript or raster. If this is on a 4.x (did you say 4.9?) then you are limited to the 1.1 Meg/sec of USB1 (I'm assuming that it's a USB printer). USB2 is 450 times faster, and may remove a bottleneck.

When something is slow, the first thing to learn is _why_ it is slow. With it running, call up systat 1 -vmstat (systat-one-dash-vmstat) and look at the bar graph from the lhs to the center of the display. If you see lots of dashes or angle brackets, the problem is with user-level code such as ghostscript . If you see lots of equal signs, then something in the kernel (a driver?) is eating the time. If you see lots of plus signs, then a lot of time is being spent fielding interrupts, which suggests that the communication between the computer and the printer is not well handled. (Parallel ports are horrible in this way.) If there is not a lot of CPU being used, then the problem lies in the printer or in the precise instructions is is being given -- or else in some other source of delay in the computer.

Hello, I own a HP LaserJet 2100, connected to my home network. According to the specifications it should be able to print 10 pages per minute. When using Windows that's not a problem. But using FreeBSD (with lpd configured with help of Apsfilter from the ports) it prints very slowly, I guess about 2 pages per minute. Is it possible to make printing go faster?
