Novell print queue disappears - requires reboot

I am running a Novell Netware 6.5 server with a non-NDPS print server and am printing from a DOS application. The application prints customer cards of 21 lines each. When I send a large number of cards to the queue, the queue receives all the output and starts sending to the printer. When the printer reaches 380 cards (approx. 8,000 lines), the print queue clears out and the following message appears on the server console: "The print queue cannot be read".
At this point the queue cannot be accessed, even by shutting the print server and starting it up again. The only way to get it back is reboot the server. All output on the queue is then lost.
The number of lines sent is irrelevant, when it prints the @8K lines, the spool crashes.

Like 1 to 255. I might be wrong, but i am pretty sure it has. You might have to UP the range to get it to carry on printing.
Here is an example:

Syntax
print /d:device /b:size /u:ticks1 /m:ticks2
/s:ticks3 /q:size /t
drive:\path\ filename /c /p

Options:
/d:device Name of printer device
Printer Ports: LPT1, LPT2 orLPT3
Serial Ports: Com1, Com2, Com3 or Com4
/b:size Sets size (in bytes) of internal buffer. Default=512 with range of 512 to 16384.
/u:ticks1 Maximum number of clock ticks PRINT is to wait for a printer to become available. Default=1 with a range of 1 to 255.
/m:ticks2 Maximum number of clock ticks PRINT can take to print a character or printer. Default=2 with a range of 1 to 255.
/s:ticks3 Maximum number of clock ticks allocated for background printing. Default=8 with range of 1 to 255.
/q:qsize Maximum number of files allowed in print queue. Default=10 with range of 1 to 255.
/t Removes files from the print queue.
drive:\path\ filename Location and filename of file to be printed.
/c Removes files from the print queue.
/p Adds files to the print queue.

The /d, /b, /u, /m, /s and /q switches can only be used once. If a different value needs to be used the computer must be restarted.

If a printer has more memory then it will be able to carry on printing.

Printer info:
PRINTER MEMORY

Like computers Inkjet and Laser printers too also have memory allowing printer jobs to be stored while others may be completing. Having a large amount of memory or available buffer space available allows for computers to send that information and allowing the computer to continue working without being bogged down by having a print job running in the background.

I am using a dot matrix printer. I do not believe this is the issue as the printer issues no alerts, nor do I see any in the Novell logs. As I watch the job list (in NWADMIN) shrinking with each line printed, it suddenly stops and a message appears stating that the queue cannot be read. I cannot get back to view the queue unless I reboot the server. Would printer memory impact the queue this way?

The printer is generally characterised by the following elements:

* Print speed: expressed in pages per minute (ppm), print speed represents the printer's ability to print a large number of pages per minute. For colour printers, a distinction is generally made between monochrome and colour print speed.
* Resolution: expressed in dots per inch (abbreviated as dpi), resolution means the sharpness of printed text. Sometimes the resolution is different for a monochrome, colour or photo print-out.
* Warm-up time: the waiting time necessary before the first print-out. A printer cannot print when it is "cold". A certain temperature must be reached for the printer to run optimally.
* Onboard memory: the quantity of memory that allows the printer to store print jobs. The higher the amount of memory, the longer the printer queue can be.
* Paper format: depending on their size, printers are able to accept different sized documents, generally in A4 format (21 x 29.7 cm) or less frequently A3 (29.7 x 42 cm). Some printers allow you to print on other types of media, such as CDs or DVDs.
* Paper feed: the method of loading paper into the printer, characterising the way in which blank paper is stored. The paper feed can change depending on where the printer will be placed (rear loading is advised for printers that will be up against a wall).* The main paper feed modes are:
