Send ESC:E to reset the printer to its default environment (PCL). The info comes from my PCL 5 Programmers Guide. You can get the most common commands at http://www.nefec.org/UPM/ccPCLfrm.htm. You can also go to the HP web site and search on PLC codes for your printer model.

RE: [U2] [OT]Postscript to a Laser on Dumb Term Aux Port
I would go with the HP printers. The $99 dollar printer may be a windows only device that relies on the host cpu to do most of the processing. This could be more problematic than the spooler. We switched from pcl only printers to combos that are capable of both pcl and postscript a couple of years ago. We found that printing large volumes of pdf files to a pcl only printer was slower than if the same model printer had a postscript driver. We did not take the time to figure out exactly why, we just switched.

People often get quite sentimental about old computer systems, the faults become so ingrained the users can no longer see them, the users get molded to fit the system.

Postscript requires more memory than pcl, it used to be i think that they also paid a royalty to adobe. But those things are fading as memory is now very cheap and i think they use 3rd party emulations(ie like ghostscript) to rasterize the document. I did a quick search on http://froogle.google.com/ there was a Brother Laser printer 1450N with postscript for a little over $200. Network printers are also faster than slave printing with serial and perhaps parallel or usb. With network printers you can also quickly redirect the receipts to another lane if one printer stuffs up. Currently, the preprinted forms/Epson arrangement is doing straight ascii printing.

So, now you know a little more about the environment what do you think ? $1500 tickets being printed on a $100 laser? So if you print 50 tickets a day = $75000so if your printer dies for a day cause you went for too cheap without a maintenance agreement or backup printer that has cost the company $75k in sales. I imagine cause each ticket is so large you are not printing a huge number the printer warmup time will be importantif you choose the wrong printer then each customer could be waiting an additional 10 seconds for the receipt. If you main computer goes down your dumb terminals are history and you might have to close the store till it is fixed. If you replace with PC's which are cheaper than your dumb terminals you can run a local pc point of sale software in the event of your main machine failure. Secondly printer running costs usually outflank the purchase price - try to work out the current running costs

The only thing that can go wrong is that the printer hangs and the whole front counter is dead. And you could go multi-printer but then you're concerned about spooler failure. I understand the thought process going on there. It's a shame that we have to code around a printer or the spooler as a single point of failure. Spoolers have been around as long as there have been multiuser systems, and yet they're still a big worry. One option is to use minimal PC's at each workstation, pump the data to the POS and have it do its own printing. A jam is localized and you can requeue if the jam is cleared. You can also reroute to a different workstation if required because the spooler isn't involved. You can use an old 286 for the workstation, but I admit this is adding some cost and complication. It's probably not worth it to re-invent the way things work over there, but I think more research into this is worthwhile. Mind you all this is happening in a retail environment with customers waiting for receipts (ever been in a supermarket when the receipt printer jams - what if that was one printer for the whole market).
