Slow printing / CUPS - process "parallel" high cpu

Hello.

I have a slackware system running cups with an HP laserJet 2100 connected via parallel port in ECP mode. Print jobs are working. Very slowly.

15K test print out of cups takes about 2 minutes to complete.

When the printout is on the way to the printer, the process "parallel" uses between 30 and 100% cpu for the 2 minute duration.

Similar utilization is seen with any print job so far.

Kernel 2.6.27.7
Cups 1.3.9

NAME
cups-browsed - A daemon for browsing the Bonjour broadcasts of shared, remote CUPS printers SYNOPSIS
cups-browsed [-v | -d | --debug] DESCRIPTION
cups-browsed has three independently switchable functions: 1. Browse Bonjour broadcasts of remote printers and create/remove local raw queues pointing to these printers. 2. Browse CUPS broadcasts of remote printers and create/remove local raw queues pointing to these printers. 3. Broadcast local queues with the CUPS protocol. OPTIONS
-v, -d, --debug Debug mode FILES
/etc/cups/cups-browsed.conf NOTES
Please take references to cups 1.6.x to include newer versions. Similarily, cups 1.5.x is intended to encompass older versions too. In environments with only cups 1.6.x servers and clients (plus cups-browsed on either server or client or both) the function described in 1. enables the automatic discovery of remote queues and their display in printing dialogues of applications and with command line tools. The facility provided by 3. means that servers running cups 1.6.x plus cups-browsed can broadcast their local queues so that clients with cups 1.5.x get these queues automatically available. The outcome of 2. is that clients running cups 1.6.x plus cups-browsed can use the CUPS broadcasts from servers with cups 1.5.x. As with browsing of Bonjour broadcasts, the created local raw queues are available to appli- cations and command line tools. SEE ALSO
