All MS-DOS application printing is done through the Windows NT spooler system. In order to know when to send a job to the spooler, there is a time-out on the printer port. Once something has been printed to the port, if this time-out passes with no more data presented to the port, the print job is sent to the spooler. On a slow computer running a complex calculation to produce the print job, it is possible that the time-out can expire during this calculation. This will cause the printout to appear over multiple pages instead of a complete page. To solve this problem, increase the time-out. Change the registry setting to the following:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WOW\LPT_timeout

The default value is 15 seconds.
