Migrating Printing from SNA to TCP/IP

  1. 1. Migrating Printing from SNA to TCP/IP The LRS Philosophy
  2. 2. Reasons for Migrating <ul><li>IP offers obvious advantages over SNA </li></ul><ul><ul><li>Lower costs </li></ul></ul><ul><ul><li>Single network protocol for all printing </li></ul></ul><ul><ul><li>Easier steps to adding printers </li></ul></ul><ul><ul><li>Open TCP/IP protocol supported by numerous output devices </li></ul></ul><ul><ul><li>Higher performance and dependability </li></ul></ul>
  3. 3. IP Printing Options from MVS <ul><li>Various points for SNA to IP ‘bridge’ </li></ul><ul><li>Many ways to ‘bridge’ gap between SNA and IP </li></ul><ul><ul><li>SNA Emulation/Gateway </li></ul></ul><ul><ul><ul><li>Server level </li></ul></ul></ul><ul><ul><ul><li>Desktop SNA emulations </li></ul></ul></ul>
  4. 4. LRS IP Philosophy <ul><li>LRS philosophy of IP printing: Begin at the source </li></ul><ul><li>Send SYSOUT data directly from MVS across TCP/IP to printer </li></ul><ul><ul><ul><li>No intermediate emulation </li></ul></ul></ul><ul><ul><ul><li>Data never touches ‘SNA world’ </li></ul></ul></ul>
  5. 5. LRS IP Printing Options <ul><li>LRS offers various options for printing host output via TCP/IP </li></ul><ul><ul><li>VPS/TCPIP </li></ul></ul><ul><ul><ul><li>LPR/LPD </li></ul></ul></ul><ul><ul><ul><li>Sockets </li></ul></ul></ul><ul><ul><ul><li>BIP ™ Support </li></ul></ul></ul><ul><ul><li>VPS/AnyQueue ™ </li></ul></ul><ul><ul><li>VPS/Email </li></ul></ul>
  6. 6. LPR/LPD Printing <ul><li>Advantages </li></ul><ul><ul><li>Ubiquitous </li></ul></ul><ul><ul><ul><li>Almost every TCP/IP host supports LPD </li></ul></ul></ul><ul><li>Disadvantages </li></ul><ul><ul><li>Inefficient </li></ul></ul><ul><ul><ul><li>Overhead associated with LPR/LPD </li></ul></ul></ul><ul><ul><li>Separators and checkpointing do not work as well as with SNA </li></ul></ul>
  7. 7. Sockets Printing <ul><li>Advantages </li></ul><ul><ul><li>Efficient </li></ul></ul><ul><ul><ul><li>No need to ‘stage’ data before processing </li></ul></ul></ul><ul><ul><ul><li>LPR/LPD ‘control file’ and associated processing not needed </li></ul></ul></ul><ul><ul><li>Separators work as they do in SNA </li></ul></ul><ul><ul><li>Commands and checkpointing also work as expected </li></ul></ul><ul><li>Disadvantages </li></ul><ul><ul><li>Servers generally do not support Direct Sockets connection </li></ul></ul><ul><ul><ul><li>Direct sockets connection cannot be made to UNIX or NT servers </li></ul></ul></ul>
  8. 8. BIP <ul><li>BIP (Bi-directional Internet Printing) enhances VPS/TCPIP Direct Sockets support </li></ul><ul><li>Advantages </li></ul><ul><ul><li>Greater control </li></ul></ul><ul><ul><ul><li>Two-way communication with printer </li></ul></ul></ul><ul><ul><ul><li>Recoverability </li></ul></ul></ul><ul><ul><ul><li>Status messages </li></ul></ul></ul><ul><ul><ul><li>Cancel key </li></ul></ul></ul><ul><li>Disadvantages </li></ul><ul><ul><li>Same as ‘sockets printer’ </li></ul></ul><ul><ul><ul><li>Does not work through servers </li></ul></ul></ul><ul><ul><ul><li>Some printers do not support BIP; most do </li></ul></ul></ul>
  9. 9. BIP Features <ul><li>Recoverability </li></ul><ul><ul><li>‘Remembers’ last page printed </li></ul></ul><ul><ul><li>Restarts at proper page after error or interrupt </li></ul></ul><ul><li>Status Messages </li></ul><ul><ul><li>Error Status codes displayed by VPS </li></ul></ul><ul><ul><li>VPS continues printing when condition cleared </li></ul></ul><ul><li>End user can cancel print using printer’s cancel key </li></ul>
  10. 10. VPS/AnyQueue Printing <ul><li>VPS ‘downloads’ output to VPS/AnyQueue </li></ul><ul><li>VPS/AnyQueue ‘forwards’ output to printers </li></ul><ul><ul><li>IP </li></ul></ul><ul><ul><li>LAN Protocols </li></ul></ul><ul><li>Advantage </li></ul><ul><ul><li>LAN level control </li></ul></ul><ul><li>Disadvantage </li></ul><ul><ul><li>LAN level control </li></ul></ul>
  11. 11. VPS/Email Printing <ul><li>VPS/Email delivers SYSOUT to email address instead of printer </li></ul><ul><li>Advantages </li></ul><ul><ul><li>Email recipient controls printing using local printer drivers </li></ul></ul><ul><ul><li>PDF, HTML, RTF (word processing), txt formats all supported </li></ul></ul><ul><ul><li>User may view document and print only selected portions </li></ul></ul>
  12. 12. Formatting Email Output <ul><li>VPS/Email has various formatting options for attachments </li></ul><ul><ul><li>PDF </li></ul></ul><ul><ul><ul><li>Ubiquitous – most users familiar with Adobe Acrobat Reader </li></ul></ul></ul><ul><ul><ul><li>Attractive output </li></ul></ul></ul><ul><ul><ul><ul><li>Font can be selected </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Font size can be selected </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Page size can be selected </li></ul></ul></ul></ul><ul><ul><li>RTF </li></ul></ul><ul><ul><ul><li>User created RTF files can be used </li></ul></ul></ul><ul><ul><ul><li>Opened by default word processor </li></ul></ul></ul>
  13. 13. Formatting IP Print Output <ul><li>Standard VPS functions allow user control of output formatting </li></ul><ul><ul><li>Landscape/Portrait </li></ul></ul><ul><ul><li>Multiple up (PostScript) </li></ul></ul><ul><ul><li>Duplex </li></ul></ul><ul><ul><li>Input tray selection </li></ul></ul>
  14. 14. Summary <ul><li>LRS IP printing is 100% IP </li></ul><ul><ul><li>No need to bridge ‘gap’ between SNA and IP </li></ul></ul><ul><li>Multiple IP printing methods </li></ul><ul><ul><li>VPS/TCPIP </li></ul></ul><ul><ul><li>VPS/AnyQueue </li></ul></ul><ul><ul><li>VPS/Email </li></ul></ul><ul><li>Flexible formatting </li></ul>
