Q61438: Slow Printing from BASIC to Network Printer Under OS/2
Article: Q61438 Product(s): See article Version(s): 6.00 6.00b 7.00 Operating System(s): OS/2 Keyword(s): ENDUSER | SR# S900122-142 | mspl13_basic Last Modified: 10-MAY-1990 BASIC prints very slowly to a networked printer under OS/2 when compared to the same printing under DOS or the OS/2 DOS box. The printing speed is the same under OS/2 versions 1.00, 1.10, and 1.20. This information applies to Microsoft BASIC Compiler versions 6.00 and 6.00b for MS OS/2, and to Microsoft BASIC Professional Development System (PDS) version 7.00 for MS OS/2. The following code, PTEST.BAS, demonstrates the slow printing speeds under OS/2. Compile and LINK the program as follows: BC /O PTEST.BAS ; LINK PTEST ; The following is the program PTEST.BAS: start = TIMER FOR x = 1 TO 50 LPRINT "ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890ABCDEFGHIJKLM:";x NEXT PRINT "Final time: "; TIMER - start The following is the output from a 386 machine running at 16Mhz with the print spooler disabled: Operating System Printer Time (seconds) ---------------- ------- ---- OS/2 Network 64 DOS box Network 6 DOS 4.01 Network 4 OS/2 Direct 46 DOS Direct 46 Note: The direct connect times are longer because the printer has no spooler, and therefore, the computer must wait for the printer to print each line. Also, a similar C routine prints at normal speed under OS/2.
